Basic Analog Operation
Broadway Limited Imports recommends that you get used to operating and
having fun with your locomotive before exploring its more advanced features or
programming options. Read through this section and be up and running with
your new Quantum equipped engine is less than ve minutes.
Running the Locomotive
Use an HO power pack with a standard direction switch. Set the switch to
run your engine forward.
• Turn the throttle up slowly until you hear the Quantum System™
come on. You will hear Start Up sounds and the dynamo will rev up
as the headlight comes on.
• Continue to turn up the throttle voltage until the locomotive starts to
move in Forward. The directional headlight will come on bright. The
locomotive will start out slowly due to special Quantum inertia effects
that resist rapid increases or decreases in speed1.
• 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 off.
• Flip the direction switch and reapply power to go in the opposite
direction.
The optional steam tender reverse light comes on in reverse while the
headlight switches to dim.
Whistle
Blow the authentic Steam Locomotive Whistle for short or long blasts – you
control the duration.
• While the locomotive is moving, ip the direction switch to turn on
the Whistle.
• Flip the direction switch back to shut off the Whistle.
The engine will not change direction when you blow the Whistle.
Note: If you ip the direction switch too slowly from one position to the

4
5
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 functions
on the locomotive.
• Turn the Bell on with a Quick ip-and-back operation of the direction
switch.
• Turn the Bell off with a second Quick ip-and-back operation of the
direction switch.
The Bell will stay on until you do another Quick ip-and-back operation of
the direction switch to turn it off, or if you interrupt the track power. If you do
a Slow ip-and-back operation, you will get a short Whistle hoot instead of
the Bell. If you try to do a very short Whistle blast using a Quick operation,
you will activate the Bell instead. If you have trouble doing the Quick ip-
and-back operation, try holding the power pack in place with your other
hand to keep the unit from slipping.
Note: When you toggle the Bell off, it will continue ringing briey with less
volume as the pneumatic clapper or swinging bell slows down, just like the
prototype.

Advanced Analog
Features
Starting the Locomotive
Most HO DC power packs with a standard reversing switch2 are suitable
for Analog operation. Generally, modern electronic type power packs will
provide better performance.
When operated with a standard DC power pack, your Quantum equipped
steam engine behaves quite differently from other locomotives you may
have operated. Unlike standard HO locomotives that start at very low track
voltages, Quantum equipped engines require a minimum amount of 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-off sounds, Air Pumps, Blower hiss and the
Dynamo revving as the Headlight comes up to its “dim” setting.
Optional Number Board Lights, Firebox Lights and Cab Lights3 will
turn on. See a table summary of Directional Lighting operation in the
DCC section of this manual.
• Continue4 to turn up the throttle voltage until the locomotive starts
to move in Forward (this voltage is called V-Start5). Steam exhaust
(chufng) will sound in sync with the motion of the drive wheels and
in proportion to the engine’s Intrinsic Inertia and Load setting (see
Sound of Power® on page 10) and the locomotive will slowly start to
move. The Headlight will switch to bright.
Locomotive Inertia Effects
Your new locomotive is pre-programmed at the factory to use
Regulated Throttle Control (RTC) in Analog (DC powered)
operation. RTC makes your locomotive operate as though
it has the mass and inertia of a prototype locomotive. As a
result, your engine will resist starting up too quickly if at rest
and will resist changes in speed once moving (see Standard
Throttle Control™ (STC™) and Regulated Throttle Control™
(RTC™) on page 8). It takes a little practice to learn to move

6
7
the throttle slowly and wait until the locomotive responds. If
you prefer that your locomotive respond almost immediately
to throttle movements on your DC power pack, it may be
reprogrammed to use Standard Throttle Control (STC). Under
STC there is no Intrinsic Inertia. The Example on page 15 of
this manual explains how to program your locomotive to use
STC.
Note: If your locomotive has two sets of drivers, you will hear two sets
of steam chuff sounds that will go gradually in and out of synchrony.
• As you slow the engine down by gradually reducing the throttle to a
little below V-start, the steam chuff labored sound volume decreases,
while Squealing Brake sounds occur as the steam locomotive comes
to a slow stop6.
If you need to turn your throttle up quite high to start your Steam Locomotive,
V-Start can be adjusted for operation with your particular DC power pack
(see Analog Programming on page 15). For recommended power packs,
consult the Quantum Analog Reference Manual (Version 3) available at
http://www.broadway-limited.com/
Doppler Effect
This effect changes the Whistle pitch and engine sounds as the locomotive
passes.
• While the engine is moving toward the observer, ip the direction
switch to turn on the Whistle.
• Wait at least one second while the Whistle is blowing.
• Flip the direction switch back and forth quickly so the Whistle does
not shut off. You will hear the Whistle and other steam locomotive
engine sounds shift in pitch as the locomotive passes by.
• Either ip the direction switch back to shut off the whistle, or continue
with long or short Whistle operations. When you are nished blowing
the whistle, the engine sounds will automatically return to normal
after a few seconds. If the Bell was on, it will shut off just before the
sounds return to normal.
Note: The faster the engine is moving, the greater the Doppler shift.
Below 15 smph, there is no Doppler shift.

Special Whistle Ending Sound
Prototype engineers would often “play” their whistles by controlling the
ow of steam to the whistle chamber. In particular, engineers often had a
signature sound associated with how they ended their whistle sequences.
Some Quantum sound sets have special Whistle Ending that can be
activated using the direction switch to produce a unique sound effect
similar to playing the whistle.
• Flip the direction switch to blow the Whistle for at least one second.
• The normal way to end the Whistle is to ip the direction switch back.
To do the special Whistle Ending, add an immediate Quick ip-and-
back operation.
Note: If you wait too long to do the Quick Flip-and-Back operation, the
Bell might turn on instead.
Note: Your Quantum may not have special Whistle Ending sounds
included.
Neutral
In Neutral, the locomotive will continue to make prototypical sounds
appropriate to its resting state.
• Enter Neutral by turning the throttle down below V-Start but not
off and wait for locomotive to stop 7. The Headlight switches to a
steady dim and Reverse Light will turn off if entering Neutral From
Reverse (NFR).
• You will hear a Short Air Let-off when the engine stops moving and
enters Neutral, and a Long Air Let-off about three seconds later
followed by Air Pumps and other background sounds such as steam
boiler Pop-Off, boiler Blow Down, and Water Injector sounds.
• After the Air Pumps start, you can also use the direction switch to
blow the Whistle or turn on or off the Bell8.
If you cannot enter Neutral, or have difculties with any of the operations,
you may need to program your locomotive for optimal use with your
particular power pack (see Analog Programming in next section).
Changing the Locomotive’s Direction without Turning off the Sound
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-

8
9
start and wait for the locomotive to stop9.
• Flip the direction switch after you hear the Short Air Let-off but before
you hear the Long Air Let-off and the Air Pump sounds turn on.
During this short time (3 seconds) the Whistle will not blow when you
ip the direction switch.
• Turn up the throttle anytime thereafter to operate the locomotive in
the opposite direction.
If you have waited until the Air Pumps start in Neutral and now wish to
change direction, you can either:
1. Turn the power all the way off, change the direction switch and turn
the power back on, or,
2. Flip the direction switch (the Whistle will come on) and then turn
up the throttle. When the locomotive starts to move in the opposite
direction, the Whistle will stop automatically and then hoot one
more time if the direction is Forward for a total of two hoots. Or if the
direction is Reverse, the Whistle will hoot two more times for a total
of three hoots10.
Note: To prevent the rst Whistle hoot from being too long, do not
delay in turning up the throttle after you have ipped the direction
switch.
Standard Throttle Control™ (STC™) and Regulated Throttle Control™
(RTC™)
Quantum locomotives have two types of Analog throttle control available,
Standard and Regulated. Both Standard Throttle Control (STC) and
Regulated Throttle Control (RTC) will apply more power to the motor as
a function of increasing track voltage beginning at the V-Start setting.
RTC includes a motor speed control feature that prevents the locomotive
from reacting quickly to changes in voltage or minor impediments such as
misaligned track joints, tight curves, rough turn-outs, etc. An engine under
STC may come to an unrealistic halt from a raised track joint or a drop
in voltage while the same engine under RTC, with its Inherent Inertia, will
continue at the same speed. RTC operates your engine as though it has the
mass and inertia of a prototype locomotive; your engine will resist changes
in speed once it is moving and will resist starting up quickly if 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.

8
9
While small obstacles will not affect the engines speed under RTC, a
continual force will slow your train down, just like the prototype. For
instance, if your steam locomotive encounters an upward 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 if it encountered an upward grade.
The type of throttle control also affects 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.
If you bring the throttle down below V-Start, the engine will slowly come to
a stop. You can, however, force 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 forces the speed to decrease faster than
RTC would normally allow. Once the locomotive slows down and regains
normal RTC operation, it will continue to decelerate slowly according to its
Intrinsic Inertia and Load setting. For instance, if 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 rst slow down rapidly as you reduced the available power to the motor,
and then would start decelerating at a rate determined by the RTC Intrinsic
Inertia and Load setting and nally coast to a stop.
STC and RTC are selected under Analog Programming (see next section).
The default is RTC.
Train Load
You can set your steam locomotive to have any of 16 different Load levels,
which represent added inertia from rolling stock (see Analog Programming
in next section). The higher the Load setting, the greater the inertia effect
during acceleration and deceleration. Level 0 is the default, which is no
Load.
Under STC, the level 0 Load setting will allow your locomotive to accelerate
or stop as quickly as the internal ywheel will allow. Under RTC, level 0
will add no additional Load to the Intrinsic Inertia already provided by RTC.
For any Load setting from 1-15, your steam locomotive will take longer to
change speed under either STC or RTC. At level 1, it will take approximately
15 seconds more to achieve full speed at max throttle11; at level 15, it will
take over 3  minutes to achieve full speed. In addition, at higher Load
settings, your engine will decelerate more slowly as you decrease your

10
11
throttle.
Sound of Power™
The steam locomotive will produce Sound-of-Power labored steam sound
effects if you have selected any of the Load settings from level 1 to 15.
Under acceleration, the Chufng sounds will be more labored until the
locomotive has achieved its nal speed where it will then produce standard
sounds appropriate to its throttle setting. Under deceleration, the engine
Chufng sounds are less labored until it achieves its nal speed where it will
again produce standard steam sounds appropriate to its throttle setting.
Helpers
Prototype Helpers are locomotives that are used to provide extra power
and/or braking for a heavily loaded train. These engines can be part of the
head-end consist or as mid-train helpers or as pushers at the end of the
train. Helper engines behave differently than the train’s lead locomotive.
Their whistles and bells are usually not operated and their lighting options
are different 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 of Helper engine has different lighting and sound
characteristics as described in the table in the next section on Analog
Programming.
Normal and Reversed Direction
Quantum also allows you to reverse the directional sense of 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 facing forwards or
backwards. However, certain features like Directional Lighting do depend
on the directional sense. For instance, if you program your engine to be
an End Helper for your consist, its tender Reverse Light operates when
the engine is moving in Reverse and the Headlight is disabled. This is
ideal for providing a Reverse Light for the consist. However, if this steam
locomotive is facing backwards at the end of a consist, the Reverse Light
faces forward and will be lit when the consist is moving Forward and there
will be no Reverse Light for the consist. The “Direction” program feature
will ensure that this End Helper’s backward facing Headlight will come on
only when the consist is backing up and the forward facing Reverse Light

10
11
will not light at all. When making up a train with different Helper types, it
is recommended that you also change its directional sense if the Helper
is intended to be operated backwards within the consist. See “Option 4
Direction”, Analog Programming, next section.
Additional Analog Operation
Your Quantum steam locomotive is equipped with our new QARC™
(Quantum Analog Remote Control) Technology, which uses special remote
control signals to operate different Quantum features without the need
for complicated and expensive digital systems like DCC. With QARC
technology, you can operate features that are otherwise available only in
DCC plus features that are not yet available in DCC. QARC will allow you
to: 1) turn on or off lights, 2) shut down and start up locomotives, 3) make
up consists easily, 4) simplify 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
Status Report or Verbal Speedometer Readout, and operate many other
features. The QARC System makes Analog operation more fun and more
prototypical than DCC by eliminating the need to congure function keys.
Every button on QARC controllers does exactly what it says. The only
major difference between QARC and DCC is that you are not able to
independently operate multiple trains on the same powered track section
at different 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 the variable
DC output from the power pack and two wires go to the track. All features
on the power pack remain the same including throttle and reverse switch
control. See http://www.broadway-limited.com/ for further information.

Entering Programming
Use this simple sequence to enter Programming using the direction
switch.
1. Apply power and turn up the throttle to hear the sound system come
on.
2. Within ve seconds of powering up, turn on the Bell with a Quick ip-
and-back operation.
3. Within three seconds of the Bell turning on, turn the Bell off with a
second Quick ip-and back operation.
4. Within three seconds, turn the Bell back on again with a third Quick
ip-and-back operation.
If you delay too long after power has been rst applied, the opportunity
to enter Programming will time out and you will need to start again by

14
15
shutting off and reapplying track power.
Once you perform the three Bell operations after applying power, the Bell
will shut off automatically and you will hear “Enter Programming” and the
Headlight and tender Reverse Lights will ash alternately off and on.
Scrolling through the Program Options
• After entering Programming, you will hear an announcement of the
rst Program Option, “Option 1 - System Volume”.
• To access other Program Options, simply ip 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. After 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: If you accidentally go to a higher option number other than the one
you wanted, simply turn the power off, 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 and Making Changes
After the verbal announcement of a Program Option, you can enter
that option by performing a Slow or Quick ip-and-back operation of
the direction switch. Upon entering a Program Option, you will hear the
current setting for 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). After a moment, you will hear the
sound playing at its current volume16.
Note: Entering a Program Option does not change the settings for that
option; it only provides information about its current value. After entering
the Program Option, additional Slow or Quick ip-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 rst Program Option, you can use
Quick or Slow operations immediately after entering Programming to

14
15
change the System Volume.
Moving on to Other Program Options or Leaving Programming
• Flip the direction switch at anytime to the opposite position, and
leave it there. Quantum will rst return to and announce the current
Program Option and then automatically advance to on to higher
options.
• Exit Programming anytime you want by turning the power off and
back on again.
Example 1: Setting Throttle Mode (Program Option # 10)
This will determine whether your locomotive uses Regulated Throttle Control
(RTC) or Standard Throttle Control (STC).
• Enter Programming after powering up your engine by turning the Bell
on, then off and then on as described above.
• After the “Enter Programming” followed by “Option One - System
Volume” announcement of the rst Program Option, ip 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 of the direction switch to enter this
option. If the throttle mode is at its default value (RTC), you will hear
“Mode equals Regulated;” otherwise, you will hear “Mode equals
Standard.”
• Use a Slow or Quick operation of 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,
“Regulated” and “Standard”.
• Once you have selected the Throttle Mode you wish to use, turn the
throttle off. 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 after powering up your engine by turning the Bell

16
17
on, then off and then on as described above.
• After the “Enter Programming” followed by “Option One - System
Volume” announcement of the rst Program Option, ip 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 of 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”.
• Use a Slow or Quick operation of the direction switch to activate
this option. Hear the message “Set throttle to V-Start” and after three
seconds the voltage will be announced17. If you move the throttle, the
new track voltage value is announced a few seconds later.
• Once throttle is set, use a Slow or Quick operation of the direction
switch to start the procedure. The engine will move18 at a slow speed
and the Bell will ring continually for about 25 seconds, indicating the
correct value is being calculated. If the locomotive does not move
during the procedure, return to the beginning of this option19 or start
over and chose a slightly higher throttle setting.
• At the end of the process, the engine will stop moving and the
Whistle will hoot, signifying the end of the operation and you will hear
the message “V-Start = X” where “X” is the new setting.
• To leave Programming, turn the throttle off, and then power up for
normal engine operation.
• Or continue to V-Max by moving the direction switch and waiting for
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 after entering this
Program Option, you will hear “Set throttle to V-Max” which is the position
where you want the full track voltage to be applied to the motor (usually
about 80% of full throttle)20. Then do a Quick or Slow operation to set V-
Max.
Note: During the V-Max setting, the engine will not move as it does under
V-Start.
Note: When double heading your Quantum equipped locomotives21, make
sure that both locomotives have similar speed/throttle characteristics by

16
17
adjusting V-Start and V-Max to prevent them from ghting each other. For
more information, download the Quantum Analog Reference Manual
(Version 3) from http://www.broadway-limited.com/

DCC Operation
These steps will allow you to start operating your Steam Locomotive
immediately using any qualied NMRA command station.
1. Select engine number 3.
2. Set your controller to 128 (preferable) or 28 (acceptable) speed step
range.
3. Start your locomotive immediately by pressing the F6 function key
to hear the engine’s Start Up sounds. Directional Lighting System
(Headlight and tender Reverse Light) will be off. Use the FL or F0 key
to turn on the Directional Lighting22.
When you reduce the throttle to zero, the engine will automatically enter
Neutral when the engine stops. You will hear a Short Air Let-off when the
engine stops moving and a Long Air Let-off about one second later followed
by Air Pumps and other background sounds23. The Directional Headlight
will go dim.
The direction of your locomotive will change when you press the direction
key.
Function Keys
The following table lists features that have been pre-assigned to your DCC
function keys. Operation of these keys can be different in the Neutral state
(locomotive stopped) and the motive states (locomotive moving in Forward
or Reverse). After you have selected your locomotive, simply press any of
the function keys listed below to produce the described effects.

** Features in parentheses indicate alternate assignments when available.
If you have a DCC command station that supports only the older 0 to 8
function key standard, you will have no way to initiate Shut Down in Neutral
with these pre-assigned feature to function key mappings. There is an
interim solution to this problem; by changing CV 41 from its default value of
32 to decimal 128, you can control Shut Down in Neutral from function F7
(instead of function F9) on your DCC command station. In Forward and
Reverse, F7 will still control the locomotive Air Brakes.
Directional Lighting Operation (F0 or FL or Headlight)
The FL (or F0, or Headlight) key toggles the Directional Headlight/Reverse
Light System24 on or off.
The defaults for Headlight and Reverse Light are off. When the FL key is
pressed, you will hear the steam electric generator (dynamo) start up and
the front head light will gradually increase in brightness as the dynamo revs
up.
When toggled on, the Directional Lights25 come on according to the table
below.

Coupler and Coupler Crash Sounds (F3)
There are two ways to use the F3 key.
• As your engine is about to couple up to a string of cars, press the
F3 key to trigger the crashing sound of 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 of the lift bar and coupling pin being raised.
This also arms the uncoupling sound effect. Press the F3 key again
while moving or in Neutral to trigger the sound of the coupler knuckle
opening and air-lines parting.
Sound-of-Power™
Your steam locomotive will produce labored Chufng sounds under
acceleration and lighter Chufng sounds under deceleration but only if CV
3, or CV 23 and CV 4, or CV 24 are set to non-zero positive values. The
level of labored sounds is proportional to the values for these four CV’s, and
how much the throttle is increased or decreased.
Under acceleration, the Chufng sounds will be more labored until the
locomotive has achieved its nal speed where it will then produce standard
sounds appropriate to its throttle setting. Under deceleration, the engine
Chufng sounds are less labored until it achieves its nal speed where it will
again produce standard steam sounds appropriate to its throttle setting.
Note: If your locomotive has two sets of drivers, you will hear two sets of
steam Chufng sounds that will go gradually in and out of synchrony.
