Basic Analog Operation
We recommend that you get used to operating and having un with your locomotive be ore
exploring its more advanced eatures or programming options. Read through this section and
be up and running with your new engine in less than ive minutes!
Running the Locomotive
Use an HO power pack with a standard direction switch. Set the switch to run your engine orward.
• Turn the throttle up slowly until you hear the sound come on. You will hear Start
Up sounds and lights will come on.
• Continue to turn up the throttle voltage until the locomotive starts to move Forward.
The locomotive will start out slowly due to special Quantum inertia e ects that resist
rapid increases or decreases in speed
1
•
• As you slow the engine down by gradually reducing the throttle, squealing brake
sounds occur as the locomotive comes to a stop.
Reversing the Locomotive
This simple operation is exactly the same as with standard locomotives.
• Bring the locomotive to a stop and turn the power all the way o .
• Flip the direction switch and reapply power to go in the opposite direction.
The diesel locomotive Reverse Light turns on and the Headlight or Optional Mars light will stop
pulsing and will switch to dim.
Horn
Blow the authentic diesel locomotive horn or short or long blasts - you control the duration.
• While the locomotive is moving, lip the direction switch to turn on the horn.
• Flip the direction switch back to shut o the horn.
The engine will not change direction when you blow the horn.
Note: I you lip the direction switch too slowly rom one position to the other, you can momentarily
lose track power as the switch is being moved through its center position.
Bell
You can turn the bell on and leave it on while you operate other unctions on the locomotive.
• Turn the bell on with a Quick lip-and-back operation o the direction switch.
• Turn the bell off with a second Quick lip-and-back operation o the direction switch.
The bell will stay on until you do another Quick lip-and-back operation o the direction switch to
turn it o , or i you interrupt the track power. I you do a Slow lip-and-back operation, you will
get a short horn hoot instead o the bell. I you try to do a very short horn blast using a Quick
operation, you will activate the bell instead. I you have trouble doing the Quick lip-and-back
operation, try holding the power pack in place with your other hand to keep the unit rom
slipping.
Note: When you toggle the bell o , it will continue ringing brie ly with less volume as the pneumatic
clapper slows down, just like the prototype.
A vance Analog Features
Starting the Locomotive
Most HO DC power packs with a standard reversing switch
2
are suitable or Analog operation.
Generally, modern electronic type power packs will provide better per ormance.
When operated with a standard DC power pack, your Quantum equipped diesel behaves quite
di erently rom other locomotives you may have operated. Unlike standard HO locomotives that
start at very low track voltages, Quantum equipped engines require a higher minimum amount
o voltage to operate the electronics. Also, the response to the throttle is much slower and more
like a prototype locomotive.
• Turn the throttle up slowly until you hear the Quantum System™ come on with air let-
o sounds. The Number Board Lights and Cab Lights
3
will turn on. The Directional
Headlight will come on dim or, i your diesel locomotive has a Mars Light, it will be dim
and the Headlight will be o . See a table summary o HeadlighVBackup Light
operation in the DCC section o this manual. You will hear the motor in the diesel
locomotive start up ollowed by the air pumps. I the diesel has two motors, you will
hear both motors start one a ter the other.
' See Locomotive Inertia Effects on page 3 for further description of this feature. Inertia effects can be programmed toStandard Throttle Control for more
responsive operation.
' Some electronic power packs do not havea reverse switch. Instead the have reverse button, which does notcause arapid change intrack polarit to
the track andis not suitable for Quantum operation. See thelist of suitable power packs intheQuantum Analog Reference Manual (Version 3)at
www.walthers.com.

Your diesel locomotive ma not have all lights depending on themodel.

Your new locomotive is pre-programmed at the actory to use Regulated Throttle
Control (RTC) in Analog (DC powered) operation. RTC makes your locomotive operate as though it has the mass and inertia o a prototype locomotive. As a result, your engine will resist starting up too quickly i at rest and will resist changes in speed once moving (see Standard Throttle Control™ (STC™) and Regulated Throttle Control™ (RTC™) on page 4). It takes a little practice to learn to move the throttle slowly and wait until the locomotive responds. I you pre er that your locomotive respond almost immediately to throttle movements on your DC power pack, it may be reprogrammed to use Standard Throttle Control (STC). The example at the bottom o page 6 in the Owners Manual explains how to program your locomotive to use STC.

• Continue
4
to turn up the throttle voltage until the locomotive starts to move Forward
(this voltage is called V-Start
5 ).
The diesel motor(s) sounds will rev up with labored
sounds proportional to the engine's acceleration and loading (see OSI Sound o
Power™ on page 4) and the locomotive will slowly start to move. The Headlight will
switch on bright and the optional Mars light will begin to pulse.
• As you slow the engine down by gradually reducing the throttle to a little below V-start,
the diesel motor(s) rev and labored sounds volume decreases, while squealing brake
sounds occur as the diesel locomotive comes to a slow stop
6
•
I you need to turn your throttle up quite high to start your diesel locomotive, V-Start can be
adjusted or operation with your particular DC power pack (see Analog Programming on pages 6-
8). For recommended power packs, consult the Quantum Analog Reference Manual (Version 3)
available at www.walthers.com.
Doppler Effect
This e ect changes the horn pitch and engine sounds as the locomotive passes.
• While the engine is moving toward the observer, lip the direction switch to turn on the
horn.
• Wait at least one second while the horn is blowing.
• Flip the direction switch back and orth quickly so the horn does not shut o . You will
hear the horn and other diesel locomotive engine sounds shi t in pitch as the
locomotive passes by.
• Either lip the direction switch back to shut o the horn, or continue with long or short
horn operations. When you are inished blowing the horn, the engine sounds will
automatically return to normal a ter a ew seconds. I the bell was on, it will shut o just
be ore the sounds return to normal.
Note: The aster the engine is moving, the greater the Doppler shi t. Below 15 smph, there is
no Doppler shi t.
Neutral
In Neutral, the locomotive will continue to make prototypical sounds appropriate to its resting state.
• Enter neutral by turning the throttle own below V-Start but not off an wait tor
the locomotive to stop
7
. The Headlight or Mars light switches to a steady dim and
the Reverse Light will turn o i entering Neutral From Reverse (NFR).
• You will hear a short air release when the engine stops moving and enters neutral, and
a longer air release about three seconds later ollowed by air pumps and other
background sounds. In addition to the pumps, cooling ans and vents will come on at
random time intervals in neutral. A ter ten seconds the cooling ans shut o i they were
on when you entered neutral.
• I the diesel locomotive is le t in Neutral From Reverse, special Low Idle state marked
by subdued throbbing motor sounds will automatically come on a ter 30 seconds (see
description o Low Idle in the section on Quantum System Sounds on page 15). The
diesel locomotive will return to normal diesel motor sounds when the throttle is turned
up.
• A ter the pumps start, you can also use the direction switch to blow the horn or turn on
or o the bell
8.
I you cannot enter neutral, or have di iculties with any o the operations, you may need to
program your locomotive or optimal use with your particular power pack (see Analog
Programming in next section).
'It is notnecessar to wait for theengine start up tofinish before entering forward. If ou tum up the throttle, thestart upsounds terminate and the diesel
locomotive will immediatel gointo normal forward operation.
5
V-Start is set at8.5 volts. It is important to note where V-Start is located on our throttle control toknow where ou willenter and leave neutral.
• Squealing brakes occur if the engine exceeds 40 scale-mph(smph)and then slows down tobelow 20smph.
'IfRegulated Throttle Control is enabled (see below) it is importantto wait until the locomotive stops on itsown. The engine's electronic inertia will keep it
moving even though ouhave reduced the throttle far enough below V-Startto stop the locomotive.In our attempt to stop thelocomotive,donot tr to reduce
thethrottle so far that all sounds gooff.
• In neutral, thebell has a distinctive turn on effect as the pneumatic clapper gains full motion tostrike the bell.

Page 4
Changing the Locomotive's Direction without Turning off the Soun
You can use the power pack's direction switch while the locomotive is in neutral to change the
engine's direction.
• Put the locomotive in neutral by bringing the throttle down below V-start and wait or the
locomotive to stop9 .
•Flip the direction switch a ter you hear the short air release but be ore you hear the
longer air release and the pump sounds turn on. During this short time (3 seconds) the
horn will not blow when you lip the direction switch.
• Turn up the throttle anytime therea ter to operate the locomotive in the opposite
direction.
I you have waited until the pumps start in neutral and now wish to change direction, you can either:
1. Turn the power all the way o , change the direction switch and turn the power back on,
or,
2. Flip the direction switch (the horn will come on) and then turn up the throttle. When the
locomotive starts to move in the opposite direction, the horn will stop automatically and
then hoot one more time i the direction is Forward or a total o two hoots. Or i the
direction is Reverse, the horn will hoot two more times or a total o three hoots10.
Note: To prevent the irst horn hoot rom being too long, do not delay in turning up the
throttle a ter you have lipped the direction switch.
Stan ar Throttle Control™ (STC™) an Regulate Throttle Control™ (ATC™)
Quantum locomotives have two types o Analog throttle control available, Standard and Regulated
Throttle. Both Standard Throttle Control (STC) and Regulated Throttle Control (RTC) will apply
more power to the motor as a unction o increasing track voltage beginning at the V-Start setting.
RTC includes a motor speed control eature that prevents the locomotive rom reacting quickly to
changes in voltage or minor impediments such as misaligned track joints, tight curves, rough
switches, etc. An engine under STC may come to an unrealistic halt rom a raised track joint or a
drop in voltage while the same engine under RTC will continue at the same speed. RTC operates
your engine as though it has the mass and inertia o a real locomotive; your engine will resist
changes in speed once it is moving and will resist starting up quickly i at rest. You will be able to
operate your locomotive at very slow prototypical speeds without having to adjust your throttle
continually to maintain speed.
While small obstacles will not a ect the engine's speed under RTC, a continual orce will slow
your train down, just like the prototype. For instance, i your diesel locomotive encounters a grade
under RTC, it will eventually slow down. Providing more throttle will slowly accelerate it back to
speed. The same engine under STC would quickly slow down or stop i it encountered a grade.
The type o throttle control also a ects how your engine decelerates. Under STC, your engine will
respond quickly to a reduction in track voltage. Under RTC, your locomotive will decelerate slowly
as you bring the throttle down. I you bring the throttle down below V-Start, the engine will slowly
come to a stop. You can, however, orce an engine to slow down rapidly under RTC by bringing
the throttle down quickly; this reduces the available power to the motor speed control circuit and
orces the speed to decrease aster than RTC would normally allow. Once the locomotive slows
down and regains normal RTC operation, it will continue to decelerate slowly according to its built-
in inertia. For instance, i your engine was running at top speed and you quickly reduced the track
voltage to just below V-Start, where the locomotive would normally be stopped, the engine's
speed would at irst slow down rapidly as you reduced the available power to the motor, and then
would start decelerating at a rate determined by the RTC inertia and inally coast to a stop.
STC and RTC are selected under Analog Programming (see next section). The de ault is RTC.
Engine Loa
You can set your diesel locomotive to have any o 16 di erent loads (also called inertia or
momentum levels; see Analog Programming in next section). As you increase track voltage, the
motor is provided an increasing portion o that power which, depending on the load setting, will
gradually accelerate the locomotive more realistically until it reaches ull speed. Level O is the
de ault, which is no load.
Under STC, the level O load setting will allow your engine to accelerate or stop as quickly as the
internal lywheels will allow. Under RTC, level O will add no additional load to the built-in inertia
already provided by RTC. For any load setting rom 1-15, your diesel locomotive will take longer to
change speed under either STC or RTC. At level 1, it will take approximately 15 seconds more to
achieve ull speed at max throttle11 ; at level 15, it will take over 3• minutes to achieve ull speed.
In addition, at higher load settings, your engine will decelerate more slowly as you decrease your
throttle.
'Onsome power packs that have high internal resistance,the track voltage ma rise slightl as the locomotive slows down and requires less power to operate.
As the engine slows, ou ma need toreduce the throttle a littlemore to remain below V-Start.
10
Standard protot pe railroad signaling is two hoots beforestarting inforward and three hoots before starting in reverse.
11
Some unloaded power packs produce excessive voltage at max throttle and will activate the Quantum high voltage circuit breaker. When this happens, our
engine will stopand emit aseries of hoots until the power is reduced toa lower voltage (see Troubleshooting, page/BJ.

Page
Soun of Power™
The diesel locomotive will produce Sound-o -Power labored diesel motor sound e ects i you have
selected any o the load settings rom level 1 to 15. Under acceleration, the motor sounds will be
more labored until the locomotive has achieved its inal speed where it will then produce standard
sounds appropriate to its throttle setting. Under deceleration, the engine sounds are less labored
until it achieves its inal speed where it will again produce standard diesel sounds appropriate to
its throttle setting.
Helpers
Prototype Helpers are locomotives that are used to provide extra power and/or braking or a
heavily loaded train. These engines can be part o the head end consist or as mid train
helpers or as pushers at the end o the train. Helper engines behave di erently than the
train's lead locomotive. Their horns and bells are usually not operated and their lighting
options are di erent or not used at all.
When you make up your train using more than one locomotive, the Quantum System allows
you to easily program how each engine will behave by selecting between a Lead engine,
Mid Helper, End Helper, or Pusher. Each type o helper engine has di erent lighting and
sound characteristics as described in the table in the next section on Analog Programming.
Normal an Reverse Direction
Quantum also allows you to reverse the directional sense o your locomotive. This is
normally not an issue with DC two-rail trains since all engines will go in the same direction
whether they are acing orwards or backwards. However, certain eatures like directional
lighting or diesel Low Idle do depend on the directional sense. For instance, i you program
your engine to be an End Helper or your consist, its Reverse Light operates when the
engine is moving in Reverse and the Headlight is disabled. This is ideal or providing a
Reverse Light or the consist. However, i this diesel locomotive is acing backwards at the
end o a consist, the Reverse Light aces orwards and will be lit when the consist is moving
Forward and there will be no Reverse Light or the consist. The "Direction" program eature
will ensure that this End Helper's backward acing Headlight will come on only when the
consist is backing up and the orward acing Reverse Light, will not light at all. When making
up a train with di erent Helper types, it is recommended that you also change its directional
sense i the Helper is intended to be operated backwards within the consist. See "Option 4
Direction", Analog Programming, next section.
A itional Analog Operation
Your Quantum diesel locomotive is equipped with our new OSI QARC™ (Quantum Analog
Remote Control) Technology, which uses special remote control signals to operate di erent
Quantum eatures without the need or complicated and expensive digital systems like DCC.
With QARC technology, you can operate eatures that are otherwise available only in DCC
plus eatures that are not yet available in DCC. QARC will allow you to: 1) turn on or o
lights, 2) shut down and start up locomotives, 3) make up consists easily, 4) simpli y Analog
programming, 5) set System Volume or Mute while train is operating, 6) trigger Coupler
Crash sounds, 7) operate prototype-like Air Brakes, 8) turn on Dynamic Brakes, 9) activate
verbal speedometer readout, and operate many other eatures. The QARC System makes
Analog operation more un and more prototypical than DCC by eliminating the need to
con igure unction keys. Every button on QARC controllers does exactly what it says. The
only major di erence between QARC and DCC is that you are not able to independently
operate multiple trains on the same powered track section at di erent speeds at the same
time.
The QARC controller, called Quantum Engineer, can be added to your existing Analog
power pack. Wiring is simple: two wires go to the variable DC output rom the power pack
and two wires go to the track. All eatures on the power pack remain the same including
throttle and reverse switch control. See our web site at www.walthers.com or urther
in ormation.

Page
Once you per orm the three bell operations a ter applying power, the bell will shut o
automatically and you will hear "Enter Programming" and the Headlight and Reverse Lights will
lash alternately o and on.
Scrolling through the Program Options
• A ter entering programming, you will hear an announcement o the irst Program
Option, "Option 1 - System Volume".
• To access other Program Options, simply lip the direction switch to the opposite
position and leave it there. Listen as each option number is announced in order.
• Flip the switch back and leave it there when you wish to stop at a particular option. A ter
you stop at an option you will hear the option number and name announced. When you
are scrolling through and stopping at Program Options, you are not making any
changes. To make changes you must actually enter the Program Option.
Note: I you accidentally go to a higher option number other than the one you wanted, simply turn
the power o , re-enter programming and start again. Once you reach the last Program Option, it
will continue to announce the last option number.
Entering a Program Option an Making Changes
A ter the verbal announcement o a Program Option, you can enter that option by per orming a
Slow or Quick lip-and-back operation o the direction switch. Upon entering a Program Option,
you will hear the current setting or that option. For unused Program Options, you will hear
"Reserved". For any volume option, you will hear "Volume equals X" {where "X" is its current
volume level setting). A ter a moment, you will hear the sound playing at its current volume16.
Note: Entering a Program Option does not change the settings or that option; it only provides
in ormation about its current value. A ter entering the Program Option, additional Slow or Quick
lip and-back operations will program new settings as described in the above table. For all level
adjustments, a Quick operation will decrease one level while a Slow operation will increase one
level.
Note: Since "System Volume" is the irst Program Option, you can use Quick or Slow operations
immediately a ter entering programming to change the system volume.
Moving on to Other Program Options or Leaving Programming
•Flip the direction switch at any time to the opposite position, and leave it there.
Quantum will irst return to and announce the current program option and then
automatically advance to onto higher options.
•Exit Programming any time you want by turning the power o and back on again.
Example 1: Setting Throttle Mo e (Program Option# 10)
This will determine whether your locomotive uses Regulated Throttle Control (RTC) or Standard
Throttle Control (STC).
•Enter Programming a ter powering up your engine by turning the bell on, then o and
then on as described above.
•A ter the "Enter Programming" ollowed by "Option One - System Volume"
announcement o the irst Program Option, lip the direction switch and leave it there.
You will hear the announcement "Option 1, 2, 3 ... etc.". Stop when you hear "ten" by
moving the direction switch back. You will hear "Throttle Mode".
•Use a Slow or Quick operation o the direction switch to enter this option. I the throttle
mode is at its de ault value (RTC), you will hear "Mode equals Regulated;" otherwise,
you will hear "Mode equals Standard."
• Use a Slow or Quick operation o the direction switch to change the throttle mode.
Repeated Slow or Quick operations will cause the throttle mode to alternate between
its two possible values (RTC, STC, RTC, STC ... etc.)
• Once you have selected the throttle mode you wish to use, turn the throttle o . When
you then power up again, your locomotive will be using the throttle mode you have just
selected.
Example 2: Setting V-Start (Program Option # 8)
This will determine the voltage (and throttle position) where your engine will leave neutral and
move out.
•Enter Programming a ter powering up your engine by turning the bell on, then o and
then on as described above.
•A ter the "Enter Programming" ollowed by "Option One - System Volume"
announcement o the irst Program Option, lip the direction switch and leave it there.
You hear the announcement "Option 1, 2, 3 ... etc.". Stop when you hear "eight" by
moving the direction switch back. You will hear "V-Start".
• Use a Slow or Quick operation o the direction switch to enter this option. You will hear
"V-Start equals X" where "X" is the track voltage value currently set to leave neutral".
"Setting an volume in Analog will also appl toDCCand vice-versa.

Page 8
• Use a Slow or Quick operation o the direction switch to activate this option. Hear
the message "Set throttle to V-Start" and a ter three seconds the voltage will be
announced
17.
I you move the throttle, the new track voltage value is announced a
ew seconds later.
•Once throttle is set, use a Slow or Quick operation o the direction switch to start the
procedure. The bell will ring continually, indicating the correct value is being calculated.
I you chose a very low setting, be patient. I you do not get a setting within a minute,
return to the beginning o this option or start over18 and then choose a slightly higher
throttle value.
•At the end o the process, the engine will move slightly and stop. The horn will hoot,
signi ying the end o the operation and you will hear the message "V-Start = X" where
"X" is the new setting.
Note: The inal value o V-Start will decrease rom the original voltage reading because resistance
in the power pack or pickups will drop the voltage slightly during this calibration procedure.
Note: Sometimes it is di icult to see the engine move unless you are watching care ully.
•To leave programming, turn the throttle o , and then power up or normal engine
operation.
•Or continue to V-Max by moving the direction switch and waiting or the next
programming option to be announced.
Example 3: Setting V-Max (Program Option# 9)
V-Max is set in the same manner as V-Start except a ter entering this Program Option, you will
hear "Set throttle to V-Max" which is the position where you want the ull track voltage to be
applied to the motor (usually about 80% o ull throttle)19. Then do a Quick or Slow operation to set
V-Max.
Note: At end o V-Max setting, the engine will not move as it does under V-Start.
Note: When double heading your Quantum equipped locomotives20, make sure that both
locomotives have similar speed/throttle characteristics by adjusting V-Start and V-Max to prevent
them rom ighting each other.

DCC Operation
These steps will allow you to start operating your diesel locomotive immediately using any
quali ied NMRA command station.
1. Select engine number 3.
2. Set your controller to 128 (pre erable) or 28 (acceptable) speed step range.
3. Start your locomotive immediately by pressing the F6 unction key to hear the engine
start up sounds. Directional Lighting System (Headlight, Reverse Light, and Mars Light
21)
will be o . Use the Fl or F0 key to turn on the Directional Lighting. Cab Lights and
Number Board Lights will be on. Cab Lights will shut o automatically a ter ten seconds.
When you reduce the throttle to zero, the engine will automatically enter neutral when the engine
stops. You will hear a short air release when the engine stops moving and a longer air release
about one second later ollowed by air pumps and other background sounds22. The Directional
Headlight will go dim or, i your model diesel locomotive has a Mars Light, it will stop pulsing and
go dim and headlight will go o .
The direction o your locomotive will change when you press the direction key.
17
Quantum s stems havea built in voltmeter that measures the track voltage and announces its value verball . Depending on the power pack, this voltage
ma be slightl different than values measured b an external meter. However, since theQuantum voltmeter uses its own values for throttle levels, it is
the correct value for thes stem.
"Seesection above: Moving on to Other Program Options or Leaving Programming.
"V-Max should not beset too low when using RTC. For most MRC™ power packs, thebest choice for V-Max is about 1.5 volts below thehighest throttle setting
as determined b theQuantum internal voltmeter.
"Do not double-head Quantum engines with standard engines and then operate the horn or bell while engines are moving. The standard engine will
reverse direction and fight with the Quantum engine.
21
Not all locomotive models have the Mars Light feature.
22
Neutral sounds also include cooling fans with vents opening and closing that turn on and off randoml .

* Quantum supports the new NMRA 0-12 unction key standard; the old 0-8 standard is not
supported.
I you have a DCC command station that supports only the older 0 to 8 unction key standard, you
will have no way to initiate Shut Down in Neutral with these pre-assigned eature to unction key
mappings. There is an interim solution to this problem; by changing CV 41 rom its de ault value
o 32 to decimal 128, you can control Shut Down in Neutral rom unction F7 (instead o unction
F9) on your DCC command station. In Forward and Reverse, F7 will still control the locomotive
Air Brakes.

Coupler an Coupler Crash Soun s (F3)
There are two ways to use the F3 key.
• As your engine is about to couple up to a string o cars, press the F3 key to trigger the
crashing sound o engine coupling. Use the F3 key again as the engine moves out to
trigger the same sound as the slack is taken up in the cars.
• Use the F3 key in neutral to produce uncoupling sounds as you disconnect cars over
uncoupler magnets. Press the F3 key once to produce the sound o the li t bar and
coupling pin being raised. This also arms the uncoupling sound e ect. Press the F3 key
again while moving or in neutral to trigger the sound o the coupler knuckle opening
and air-lines parting.
23
Explicit lighting control features for headlight, reverse light and Mars Light can beassigned to DCCfunction outputs. (See OSI DCC Reference Manual,
version3)
24
Quantum uses constant voltage lighting that is independent of track voltage.

Soun -of-Power™
Your diesel locomotive will produce labored diesel motor sounds under acceleration and lighter
diesel motor sounds under deceleration but only i CV 3, or CV 23 and CV 4, or CV 24 are set to
non-zero positive values. The level o labored sounds is proportional to the values or these our
CVs, and how much the throttle is increased or decreased.
Diesel Motor RPM: Quantum has all eight diesel motor throttle "notches" ound on prototype
locomotives. As you increase the throttle, you will hear the RPMs increase or every increase in
ten speed steps (at 128 speed step setting). Idle is considered Notch 1 and occurs or speed step
0. Notch 2 ranges rom 1 to 10, Notch 3 rom 11 to 20, Notch 4 rom 21 to 30, etc. I your
controller has an option to increment or decrement your throttle set setting by ten speed steps, it is
very easy and predictable to set your notch value.
Horn an Bell Buttons (F2, F1)
Some DCC controllers have separate horn and bell buttons along with Function Keys assigned to
Horn and Bell operation. The horn is usually assigned to F2. The F2 key behaves di erently than
using the horn button.
•Pressing the F2 key and releasing it will cause the horn to come on and stay on, until
you press F2 again 25.
• Pressing the horn button will blow the horn only as long as you are holding it down.
Pressing the F1 key and releasing it will cause the bell to come on and stay on, until you press F1
again. There is no di erence in operation between the bell button and its corresponding Function
Key.
Doppler Operation (F6)
With DCC, you can trigger the Doppler e ect by quickly interrupting the horn signal in the same
way it is described under Analog control. Or you can use the Function Key dedicated to the
Doppler e ect.
•Start the horn and/or bell by pressing and releasing their unction keys26.
• Press F6 to hear the Doppler shi t. A ew seconds a ter the horn button is turned off with
the F2 key the engine sounds return to normal
27.
Squealing Brake an Flange Soun s (F7)
•Quantum provides automatic brake squeal as an engine slows to a stop. The operator
can also control squealing sounds or continuous and variable brake sounds or
protracted stops or to simulate the sounds o squealing wheel langes on curved track.
•Squealing Brakes come on automatically when the speed is reduced rom high-speed
travel (over 40 smph) to less than 20 smph.
•Pressing the F7 key when the engine is moving at any speed will manually activate
Squealing Brake sounds, and repeated pressings while the Squealing Brake sounds
are occurring will continue the sounds uninterrupted.
Note: I you slow the engine too quickly, the brake sounds will terminate abruptly when the
locomotive stops and enters neutral.
Note: I you lower your throttle to speed step 0 on a moving locomotive, the F7 key will apply Air
Brakes as long as the locomotive continues moving. See next section.
Air Brakes (F7)
I you have selected any non-zero deceleration inertia or momentum value in CV 4 and/or CV 24,
the F7 key can be used to apply brakes to stop the engine more quickly than it would normally
stop rom the inertia settings
28.
To use Air Brakes:
•Turn the throttle down to speed step 0 on a moving engine; this enables the F7 key to
act as a brake.
•Press the F7 key. Hear a brie brake squeal sound and air being released rom the
brake lines continually. The longer the air is released the greater the braking action.
•Press the F7 key again to stop the air release. The train will continue to slow at the last
braking value.
• I you want to apply more braking, press the F7 key again to release more air. When you
reach the desired amount o braking, press F7 again to stop the air release.
Note: I you continue to release air ( or over 24 seconds total), all the pressure will be
released and brakes are on ull; you will hear no urther air release sounds.
•Turn up the throttle to any value above Oto release the brakes; this returns the engine's
deceleration to a value determined by the sum o CV 4 and CV 24.
• I the engine is in Neutral when the F7 key is pressed, a long air release sound
simulates setting the brakes. However, no braking e ect is activated29.
I the throttle is set to any speed step except 0, air brakes are not enabled; instead the F7 key will
now manually activate squealing brake/ lange sounds but will not a ect the engine's deceleration.
25
Since the protot pe horn usescompressed air, ou ma hear the air pump sounds tumonafter thehorn is operated.
26
If ou donottum on either horn or bell, the doppler shift will still occur but will be less dramatic.

Automatic Features with "Take Control" Operation
The Quantum System allows the operator to take control o certain automatic eatures by using
their associated unction key. Once you "Take Control", the eatures will no longer have automatic
operation and you will control their operation and their state with their unction key commands.
Automatic and Take Control operations are described in the table below.

disabled. Therea ter, the ans will respond only to the state o the F4 unction. Automatic operation
will be restored i the power is shut down and reapplied or i the F6 Start Up key is double pressed
in neutral (see the description o Start Up on the ollowing page).
Three Stages of Shut Down:_1 Disconnect, 2. Stan by, 3. Total Shut Down (F9)
Engine Shut Down has three distinct stages that you can control. Each stage is entered by double
pressing the F9 key30.
Stage One: Disconnect
• Double press the F9 key in neutral to enter Disconnect. You will hear a long air let-o .
•To leave Disconnect, either double press the F6 Start Up key described in the Start Up
section or double press the F9 key again to reach the next stage o Shut Down,
Standby.
I you double press the F9 key in neutral, the motor drive will be disconnected. Once you hear the
long air let-o , the throttle can be moved up and down without the diesel locomotive moving. As
the throttle is moved up or down, you will hear the diesel motor rev up and down in proportion to
the throttle setting.
Note: You can also turn on the Dynamic Brakes (see description o Dynamic Brakes below) to
create Sound-o -Power as the throttle is moved up and down. Engineers on prototype diesels use
the Dynamic Brakes to load the diesel motor-generator to test its output and e iciency while the
locomotive remains stationary.
Stage Two: Stan by
•Double press the F9 key while in Disconnect to enter Standby. You will hear a long air
let-o ollowed by a special "Low Idle" sound. The Directional Lighting and Mars Light
will then shut down. The motor will remain disconnected, while the Air Pumps,
automatic Cooling Fan Operation, Number Board Lights and Cab Lights will continue to
operate. In Standby, the engine will not respond to throttle or unction keys31. The three
exceptions are the F6 Start Up Function Key, the F8 Mute Key {described below) and
the F1O Status Key (described below).
•To leave Standby, either double press the F6 Start Up key described in the Start Up
section or double press the F9 key again to reach the inal stage o Shut Down, Total
Shut Down.
Note: Standby is ideal or leaving your engines running on a siding. Besides the low idle motor
sounds, the engine will not respond to accidentally changing the throttle setting or pressing the
unction keys.
Stage Three: Total Shut Down
•Double press the F9 in Standby to enter Total Shut Down. You will hear a long air let-o .
•To leave Total Shut Down, double press the F6 key.
I you double press the F9 key while in Standby, you will hear a long air let-o a ter which the
locomotive will advance to Total Shut Down. The air pumps will turn o , ollowed by the Number
Boards and the sounds o the cooling ans shutting o , the louvers closing and the diesel motor
shutting down. A ew seconds later you will hear the engineer's door open and then shut. In Total
Shut Down, the engine will not respond to throttle or unction keys. The two exceptions are the F6
Start Up Function Key {described below) and the F1O Status Key (described below).
"' Double pressingensures that Shut Down stages are notentered or exited accidentall . Double pressing is defined as two F9commands sent within two
seconds. Notethat the F9 ke ma have to bepressed three times,due to the commandstationand locomotivehavingdifferent initial states for F9.
" Function ke s will onl produce ashortair let-off.

Page 12
I power is turned o at any stage o Shut Down (Disconnect, Standby or Total Shut Down) or
during a Shut Down procedure, the engine will remember the last Shut Down stage where it was
during power down, and will power up in the same stage. I Start Up is initiated during any o the
above Shut Down procedures, Shut Down is aborted and the engine returns to normal operation.
Note: Total Shut Down allows the operator to take the engine "o line" (turn o sounds, lights,
ignore throttle settings and unction commands) independent o the operating session; that is, the
engine will still be "o line" when power is reapplied or the next operating session.
Dynamic Brakes (F5)
The prototype diesel locomotive has Dynamic Brakes that cause the train to slow down by using
the traction motors in generator mode. This helps dissipate the energy o a moving train by
converting it to electrical power, which is then applied to a large air-cooled resistor load in the
locomotive.
•Pressing the F5 key in Forward or Reverse will set the locomotive diesel motor sound
to idle at the lowest Sound o Power setting and turn on the power ul Dynamic Brake
Cooling Fans.
•Pressing the F5 key in neutral will turn on the Dynamic Brake Fans while diesel motor
sounds remain at idle.
The Dynamic Brake unction automatically turns o when entering or leaving neutral, or the speed
o the locomotive drops below 7 smph32, or i the throttle is turned up. The Dynamic Brakes cannot
be turned on in Forward or Reverse unless the engine is traveling over 8 smph.
Note: In contrast to Air Brakes (F7), Dynamic Brakes do not increase the deceleration rate
speci ied by CV 4 and CV 24.
Start Up (F6)
I your diesel locomotive is in any stage o Shut Down, you can return your locomotive to normal
operation by double pressing the F6 Key. Start Up will be di erent or each stage o Shut Down,
but all will start up with a long air release and will enter normal operation.
Start Up from Disconnect: I you double press the F6 key in Disconnect, the diesel locomotive will
produce a long air let-o , dynamic brakes will shut o (i on) and the locomotive will enter normal
operation.
Start Up from Stan by: I you double press the F6 key in Standby, the diesel locomotive will
produce a long air let-o , Directional Lighting will turn on (i previously on), the diesel motor sound
will change rom the special Low Idle to regular Idle, and the engine will enter normal operation.
Start Up from Total Shut Down: I you double press the F6 key in Total Shut Down, the diesel
locomotive will produce a long air let-o , you will hear the engineer's door opening and closing,
Cab Lights come on (i available and Normal or Lead Helper), Number Boards come on (i
available and Normal or Lead Helper), Directional Lighting turning on (i previously on), ollowed
by the vents opening, the diesel motor starting up, the pumps starting up, and the locomotive
entering normal operation. During the Start Up procedure, none o the unction keys are active.
I the throttle is turned up rom zero during any o the above Start Up procedures , the Start Up
procedure will abort and the engine will enter normal operation.
Note: Whenever a Start Up command is sent, regardless o whether the engine is in Shut Down
or operating normally, the Quantum System will automatically restore all Automatic Operations.
Mute (F8)
The Quantum System allows you to reduce the System Volume to a lower level or increase it back
to its original setting using the F8 unction key. This is use ul when you need to reduce the sound
to engage in a conversation or to answer the phone. I you have many trains operating at once,
you can reduce the volume on all those that are running in the background o the layout and
increase the volume o the closest engine. The Mute eature changes the sound gradually over a
second or two, which allows the sound to increase or decrease realistically as the locomotive
approaches or recedes rom the observer.
•Press the F8 key in Neutral or Forward/Reverse to gradually decrease or increase the
locomotive's volume.
Note: Mute state is not maintained i power is turned o and back on; the locomotive will return to
ull volume setting.
Note: Mute volume can be programmed in CV 51.1.
Status (F1O)
Quantum provides verbal in ormation about the engine's current operating state when the
locomotive is in neutral or the engine's current speed in scale miles per hour when the locomotive
is moving.
• Press the F1O key in Neutral; the locomotive will verbally report irst its currently
enabled long or short loco ID ollowed by its consist ID i it has one, ollowed by its shut
down state (Disconnect, Standby or Shut Down).
•Press the F10 key in Forward or Reverse; the locomotive will verbally report the
locomotive's speed in scale miles per hour.
Note: When Status Report is activated, the locomotive's sounds will reduce to one hal their
current volume settings during the verbal report and then return to normal volume when the report
has ended.

Function Key Operation in Neutral
Some Function Keys used in Forward and Reverse will have di erent e ects in Neutral:
• The F7 key produces Brake Squeal or a moving engine but produces a long air let-o
in neutral.
• Pressing F6 results in Doppler shi t or a moving engine but activates Start Up in
neutral.
• Pressing F9 produces a short Air Let-o in a moving engine but activates Shut Down in
neutral.
Note: Horn, Bell, Doppler Shi t, Squealing Brake and Neutral sounds are described in detail on
page 15, in the Quantum S stem Sounds section o this manual.

Quantum System Soun s
42
Diesel Motor Rev: Quantum allows diesel motors to be operated with all eight notches
corresponding to the throttle notches used on the prototype. As the throttle is turned up, the diesel
motor RPM will increase in ixed increments until the maximum RPM occurs at notch 8.
Diesel Turbo: Turbo appliances are used to improve the engine's horsepower on modern diesels
by pumping air into the intake mani old under pressure. The power to operate the turbo comes
rom the diesel motor's exhaust pressure, which causes the turbo high-pitched whine to lag
behind the revving o the motor. Quantum systems use a separate sound or the turbo to allow it
to lag behind revving the motor up and to "hang" or a ew seconds when the motor is revved
down.
Low I le: Low Idle is used on prototype engines to maintain a warm and ready locomotive with a
minimum o uel consumption. The special Low Idle sound has a lower base throb and is less
harsh than the normal idle.
Cooling Fans: The enormous diesel motors and generators enclosed in the diesel cab need
ventilation to stay cool. All diesel locomotives have power ul cooling ans on the roo to draw
outside air through louvers on the sides o the locomotive, which is blown across large radiators.
You will also hear the sounds o louvers opening be ore the ans start. When cooling ans shut
down, you will hear the louvers close.
Air Pumps: When an engine is sitting still, the pumps come on in a steady beat to replace the air
lost rom the brake air release or any other air operated appliances. Once the pressure is up, the
pumps only turn on occasionally to maintain the pressure. Diesel Air Pumps are operated directly
rom the motor and are quite noticeable when turned on in a non-moving locomotive. In Forward,
you will hear the air pumps come on soon a ter the horn is operated to maintain the air pressure.
Appliance Air Release: Compressed air is used on engines or operating various appliances.
You will hear both a short air release or long air release at various times.
Air Brakes: When prototype train brakes are applied, air is released rom the brake lines to
reduce the pressure. The more the pressure is reduced, the greater the braking. You will hear a
continual air release sound rom the diesel locomotive model as braking is continually increased.
The longer the air is released, the quicker the diesel locomotive model will slow down. Once all
the pressure is released, the engine will continue at maximum braking which can still require a
long stopping distance depending on your load settings. DCC and QARC4
3
nly.
Brakes Squeal: You can hear the brakes squeal on prototype locomotives when the engine is
moving slowly and can become particularly loud when the wheels are just about to stop turning.
Listen at slow speeds or automatic brake squeal sounds and the inal distinctive squealing
sounds as the diesel locomotive slows to a stop.
Dynamic Brakes: Electric motors can act as motors or generators depending on whether they
are using power or generating power. When used as generators, the traction motors are
disconnected rom taking power rom the locomotive's prime mover, and instead are connected to
large resistor grids in the roo . By increasing the resistive load on the traction motors, the traction
motors become harder to turn and act as brakes or the locomotive. The electric power
generated by turning the
"Notall features areincluded on ever diesel. Consult our Diesel Model Specificationssheet fora list of features and sounds for our model.

Page 18
traction motors is dissipated as heat by the resistor grid. These resistor arrays get quite hot and
require cooling. When dynamic brakes are turned on in the Quantum equipped diesel locomotive,
the diesel motor sound drops to notch 1 and the Dynamic Brake cooling an sounds come on.
Since Dynamic Brakes are relatively ine ective at low speeds, the Dynamic brakes will shut o
automatically below 8 smph. DCC and QARC nly.
Horn: The Quantum System uses authentic locomotive sounds whenever possible. All Quantum
horns are engineered by our sound experts to give you the most authentic e ects. I you blow the
horn brie ly, you will produce a realistic short horn sound or "hoot".
Bell: Diesels and Electric locomotives, as well as larger steam engines, usually have
pneumatically operated mechanical bells. Small steam engines o ten have hand-pulled bells.
During turn-on in neutral, hear the pneumatic clapper gain greater throw with each stroke until it
inally sticks the bell. During shut down in neutral, you will hear the bell ade out along with the
short air release sound associated with turning this appliance o .
Doppler Run-by: The engine sounds get louder as the train approaches, then immediately drop to
a much lower pitch and lower volume as the train passes by. With a little practice you can change
the pitch exactly when and where you want. Doppler shi t is based on the speed o the engine, so
the sounds change more dramatically when the engine is running aster. A ter the Doppler shi t
has occurred and the horn is no longer being blown, the bell shuts o automatically and
locomotive sounds return to normal.
Coupler: To give you the most authentic coupler sounds, OSI has identi ied three distinct types o
coupler activity. The irst is when the coupler is armed where you will hear the clanking sound o
the coupler li t bar and coupler pin raising. The next is the coupler opening, with the hiss o the air-
lines parting. The third is when the locomotive couples up to its load o cars, and you hear the
crash as all the cars bunch together rom the impact. DCC and QARC only.
Flanges: When a train enters a curve, the langes on the wheels ride up on the inside o the rail
and squeal. Recreate this squealing e ect by pressing and releasing the Brake Squeal/Flanges
button quickly and repeatedly as necessary. DCC and QARC only.
Special Operation an Troubleshooting
For a ull description, see the Troubleshooting section in the Quantum DCC Re erence Manual
(Version 3) at www.walthers.com.
With some command stations, using the horn button to activate the horn, and, while this button is
held down, activating the F6 Doppler Key, will cause the horn to shut o instead o causing a
Doppler shi t e ect.
We have experienced intermittent and independent horn signal interruption with some DCC
command stations, causing unexpected Doppler shi ts. I this happens requently, you may want to
disable the horn Triggered Doppler (CV 51.2).
Switch Operation with Magnetic Wan (Analog an DCC)
•The locomotive is equipped with a special switch located directly under the plastic
diesel roo that can be activated by the Magnetic Wand (enclosed) without having to
disassemble the locomotive. The switch can be used to change the volume o your
sound system or to reset the engine to actory de aults.
Manual Volume A justment (Analog an DCC)
• Locate the switch relay area on the locomotive's roo as shown in the Diesel Model
Specifications sheet that was included with your model.
•Power up engine and leave in Neutral. Make sure bell is not on.
•Place the enclosed magnetic wand over this switch area on the locomotive's roo
perpendicular to the track and wait as you hear the volume increase or decrease in
incremental amounts as the horn hoots about every second. Move the wand away and
again place it over the switch area to change the direction (louder or so ter) o the
volume change. Remove the wand when you reach the desired volume level.
Note: Volume can also be adjusted digitally using the programming methods described in the
programming sections o this manual.
Resetting your Engine to Factory Default Values with Magnetic Wan (Analog an DCC)
In case your engine's sound and control system misbehaves and turning the power o or 15
seconds does not return it to normal operation, you can reset your locomotive to original actory
values.
• Locate the switch relay area as shown in the Diesel Model Specifications sheet.
•Turn o the power.
•Place the Magnetic Wand over the switch area and apply power and leave the wand
there until you hear the word "reset". Your engine is now reset. Remove the wand
be ore the manual volume adjustment is activated.

The locomotive has now been returned to original actory de aults including all DCC and Analog
values.
Turn your Locomotive Off or On using the Magnetic Wan (Analog Only)
Your locomotive can be selected (turned on) or deselected (turned o ) using the Magnetic Wand.
When the locomotive is deselected, it will remain unmoving and silent with lights o and will not
respond to changes in track voltage or Analog horn or bell signals or programming commands.
To shut o a locomotive:
• Enter neutral and turn
on
the
bell .
• Place the Magnetic Wand over the switch area. The bell will shut o ollowed by the
locomotive shutting down and all lights will go o .
To turn on a locomotive:
• Make sure track power is applied. Place the Magnetic Wand over the switch area on the
locomotive. The lights will come on ollowed by start up sounds. The engine is now
selected and will respond to track voltage and all bell and horn signals.
Note: You can turn o an engine in a consist even though it has been programmed as a Helper
type with disabled bell and horn sound. Simply send the bell signal command. Even though the
bell will not be heard, the Magnetic Wand will shut the locomotive down.
Using the Magnetic Wand makes it easy to turn engines o or on in Analog without the need or
blocks. You can place engines on sidings and shut them o without having to switch power o in
that track section. You can make up consists by bringing up each locomotive one at a time. A ter
you couple each engine to the consist, shut it down with the Magnetic Wand. When all engines
are in place, select each engine in turn with the Magnetic Wand until all locomotives are
running. You can now operate the consist as a single unit. When you break up the consist, you
irst deselect all engines one at a time and then select each one in turn as you disconnect and
pull away rom the consist.
High Voltage Circuit Breaker (Analog an DCC)
Your locomotive is designed to operate on normal HO track voltage supplied by most HO power
packs. I track voltage exceeds 21.5 volts peak, the motor drive circuit will automatically shut
down and the engine will coast to a stop, while the Quantum System alerts you to the problem
through a continuous series o hoots. This built in sa ety eature protects Quantum and the
electric motor rom excessive voltage
5
•
• To restart your engine, reduce the track voltage until the hooting stops and the motors
re-engage.
Program Track Operation (DCC)
This locomotive con orms to NMRA standards or program track operation. However, the
Quantum sound system requires more current to operate than standard decoders and may not
respond to the limited program track power rom some command stations. I your program track
will not respond properly, all CVs in your locomotive can be programmed in Ops Mode.
Reasons why Your Locomotive is Silent or will not Start (Analog an DCC)
In case your engine remains silent a ter power up and turning the power o or 15 seconds does
not return it to normal operation, try the ollowing suggestions to bring your engine back to normal
sound operation.
• Make sure the engine has not been Muted with the F8 Key.
• Check to see i your manual volume (using Magnetic Wand) or digital volume has been
turned all the way down.
• You may have shut your engine down in DCC using the F9 key, which remains in e ect
in Analog or it has been shut down using the Magnetic Wand in Analog. Go back to
DCC operation and start your engine with the F6 key
6
. Once started, you can return to
DC or DCC operation. Or use the Magnetic Wand in Analog which selects and starts
the engine i shutdown.
• I the above methods do not start your engine, reset your locomotive to actory de ault
values as described above.
"Thehigh voltagecircuit breaker will sometimes activate if the load(inertia or momentum) feature is used. Most power packs havesubstantial series
resistance,which lowers the track voltage when theengine is drawing power.However, withaloadsetting,the enginedoes not require much power when it first
starts moving.If the throttle is turned upall the wa before theenginegains speed, the track voltage will beunusuall highandcan trigger the high voltage circuit
breaker.
