Set Up Checklist
- Lubricate the locomotive
- Check to see whether the battery needs to be charged for full sound effects
- Apply power to run as described in the Basic Operating Section of this manual
Lubrication
You should lubricate the engine to prevent it from squeaking. Use
light household oil and follow the lubrication points marked “L”
(shown below). Do not over-oil. Use only a drop or two on each
pivot point.
Checking the Battery
You may find, if your locomotive was built several months before you set it up,
that the rechargeable battery has run down and needs to be charged before
operating. If you notice that the sounds are garbled, test and charge the engine as
described in the "Self-Charging Battery Back-Up" on page 17.

Basic Operation
The Throttle knob controls how fast your train will travel. Turn the throttle knob
up ½-way, until the engine lights shine bright. Put the engine into motion by
pressing the Direction button on your transformer once. (hold it for approximately
1 second)
If the engine does not begin to move as soon as you firmly press the Direction
button, you may not have sent enough voltage to the track to make the train move.
Turn the throttle up a bit higher until the train begins to move.
Activating Features
Throttle - To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while
turning counterclockwise will decrease voltage and speed. The engine will maintain
the speed you set after you release the throttle until you turn it again to change the
voltage and speed.
Bell - To sound the bell, in an engine equipped with a bell firmly press and release
the Bell button. To turn the bell off, press and release the Bell button again. The
bell will continue to ring from the time you turn it on until you press and release
the button again to turn it off.
Horn/Whistle - To sound the Horn/whistle, firmly press the Horn/Whistle
button. The horn or whistle will sound for as long as you continue to depress the
button. It will stop when you release the button.
Direction - Your train is programmed to start in neutral. The train will always
cycle neutral-forward-neutral-reverse with each press and release of the direction
button. The engine is programmed to restart in neutral each time the track voltage
is turned off for 25 seconds or more.

Proto-Sound® 2.0 Operating Instructions
This manual contains the operating instructions for Proto-Sound® 2.0 in
conventional mode only. Instructions for accessing DCS command mode features
accompany the DCS Remote Control System equipment.
Activating Proto-Sound® 2.0 Conventional Mode
Features
Because Proto-Sound® 2.0 is an all-new system developed by M.T.H.'s own
research and development team, it operates differently from original Proto-Sound.
Most Proto-Sound® 2.0 features are automatically enabled, and Reset has been
eliminated, so there is no need to program features as with original Proto-Sound.
Although the new system is easier to operate than original Proto-Sound, you
should read these instructions thoroughly before using Proto-Sound® 2.0 features
in order to prevent harm to yourself or your equipment.
Proto-Sound® 2.0 features are activated by sequences of Bell and Horn button
pushes described below. Please read the full descriptions of each feature before
using it. To use these buttons to activate features rather than to blow the horn or
ring the bell, you should press the buttons firmly, but rapidly with a ½-second
pause between button presses. You may need to practice your timing to make this
work smoothly.

Operating Modes
1. Manual Mode
Upon initial power application, the engine will start up in manual mode. The chart
below lists the features available to the operator when in Manual Mode. Different
features are available when operating in Learn and Auto Modes, which are
described later.
Transit Announcement Sounds (TAS)
Your Proto-Sound® 2.0 model is equipped with operator controlled Transit
Announcement Sounds, hereafter known as TAS. This easy-to-use feature plays
digitally reproduced transit announcements and platform action sounds whenever
you activate and stop your engine. No additional wires or modifications are needed
on your layout to enjoy these amazing sound effects. These different sounds are
heard each time you give a long bell button press. The entire TAS sequence is
designed to simulate the arrival, disembarking, embarking, and departure of a
transit stop. The sounds include the driver announcing the stop and the upcoming
stop, passenger disembarking and embarking sounds, driver to passenger requests,
door openings and closing and general transit stop sounds. After the station
sounds have finished, the engine will shift back into gear and, if the throttle is set
high enough, will pull away from the station. To activate the TAS, press and hold
the bell button for approximately 2 seconds.
If you do not wish to stop at the station that is announced after activating TAS,
press and hold the bell button again without throttling down the train.

2. Learn Mode
In Learn Mode, the engine may be programmed with either an "Out & Back" route
or a "Loop" route. An "Out & Back" route begins at the 1st station (as
programmed by the operator), stops at intermediate stations, ends at the last
station, then reverses its route until it reaches the 1st station. A "Loop" route
begins at the 1st station (as programmed by the operator), stops at intermediate
stations, ends at the last station, and then begins the route over again at the 1st
station.

To program stations:
1. Running in Forward, stop the unit at the desired location for the first stop by
pressing the direction button. Note: if you stop the engine with the throttle
control, you must re-apply power so that the engine goes into neutral and does not
shut down.
2. Enter Learn Mode by pressing Horn - Bell - Bell - Bell - Bell. The train will then
announce that you have entered Learn Mode.
3. Press and hold the Bell button to scroll through the available stations until you
hear the one that you would like to be your first stop. Release the button quickly as
soon as you have heard the desired stop name.
4. Press and hold the Horn button until a "saved" response confirms that station's
location and name are saved in memory.
5. Proceed to the next stop by pressing the Direction button.
6. Press the Direction button to stop the train again when you have reached the
next desired station location.
7. Using the Bell button, select the name of the station, then save using the Horn
button.
8. Repeat steps 5-7 until you are ready to program the last stop in the route.
9. The manner of saving the last station in the route determines whether the route
will be an "Out & Back" or "Loop" route.
"Out & Back"
Follow steps 5-7 to save the last station. After you press the Horn button and
the sound system plays the "Saved" confirmation, press the Horn button
again. Another "Saved" confirmation will play and the car will exit Learn
Mode and enter Manual Mode.
“Loop"
Follow steps 5-7 to save the last station. Press the Direction button once to
start the car in forward and stop the car at the location of the first stop by
pressing the Direction button. Press the Bell button as many times as is
necessary to hear the name of the first stop. Press the Horn button until
the"Saved" confirmation is played. The car will then automatically exit Learn
Mode and enter Manual Mode.

Notes:
Always approach a desired station stop location while running in Forward.
Learn mode counts distance traveled, not actual physical locations. However,
unlike an automobile's odometer, Proto-Sound 2.0 Learn Mode does erase
distance when traveling in reverse. If you operate your car past the desired stop
location, you may back it up to the desired stop location, however you must put
the car into forward and then neutral again before saving the stop name and
location into memory.
3. Auto Mode
When you have finished programming your stations in Learn the car will be in
Manual Mode. Running in Forward, stop the car at the location of the first
programmed station by pressing the Direction button. Press Bell Horn Horn to
put the train into Auto Mode. Press the Direction button again to begin operation
in Auto Mode. Because Auto Mode operation begins at the first stop, the next stop
announced will be the second stop.
Notes:
The engine will always power up in Manual Mode.

Proto-Coupler Operation
This locomotive is equipped with one or more coil-wound Proto-Couplers for
remote uncoupling action. Because Proto-Couplers are controlled through the
Proto-Sound 2.0 microprocessor, they do not require an uncoupling track section
or modification to your layout to function. You can fire a coupler from neutral or
while in motion. Use the code shown below to fire the coupler(s).
Rear Coupler:
To fire the rear coupler, quickly tap the Bell button once followed by three quick
taps of the Horn/Whistle button, allowing approximately ½ second to lapse
between each quick button press. The sound of the liftbar and air line depletion
will play, and the knuckle will be released.

Front Coupler:
To fire the front coupler (if your engine has one), quickly tap the Bell button once
followed by four quick taps of the Horn/Whistle button, allowing approximately
½ second to lapse between each quick button press. The sound of the liftbar and
air line depletion will play, and the knuckle will be released.
Speed Control:
M.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities that
allow the engine to maintain a constant speed up and down grades and around
curves, much like an automobile cruise control. You can add or drop cars on the
run, and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature activated,
you can opt to turn it off. This means the engine's speed will fall as it labors up a
hill and increase as it travels downward. It is also affected by the addition or
releasing of cars while on the run. Because the engine will run more slowly at a
given throttle voltage when speed control is on than when it is off, you should
adjust the throttle to a lower power level for operation with speed control off to
avoid high-speed derailments. When speed control is off, the volume will drop to
allow for better low voltage operation.

To turn speed control on and off, put the engine in neutral, then quickly tap the
transformer's horn/whistle button one time then quickly tap the Bell button two
times, allowing approximately ½ second to lapse between each quick button press.
Repeat the 1 horn/whistle, 2 bells code to return it to the other condition. You
will want to do this during the initial neutral upon start-up if you ever couple this
engine to another engine that is not equipped with speed control to avoid
damaging the motors in either engine. Each time you shut down the engine
completely, it will automatically turn speed control on.
Lock into a Direction:
You can lock your engine into a direction (forward, neutral, or reverse) so that it
will not change directions. To do this, put the engine into the direction you want
(or into neutral to lock it into neutral), run it at a very slow crawl (as slowly as it
will move without halting), and quickly but firmly tap the Horn/Whistle button
once followed by three quick taps of the Bell button, allowing approximately ½
second to lapse between each quick button press. Two horn/whistle blasts will
indicate that the engine has made the change. The engine will not change direction
(including going into neutral) until you repeat the 1 horn/whistle, 3 bells code to
return the engine to its normal condition, even if the engine is kept without power
for extended periods of time.

To override the settings you currently have assigned to the engine and reset it to its
factory defaults, while in Neutral tap the Horn/Whistle button quickly once,
followed by five quick taps of the Bell button, allowing approximately ½ second to
lapse between each quick button press. Two horn/whistle blasts will indicate that
the engine has made the change.

Maintenance
Lubricating and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
Regularly lubricate all axles and pickup rollers to prevent squeaking. Use light household oil,
such as that found in M.T.H.'s maintenance kit. Do not over oil. Use only a drop or two on
each pivot point.
The locomotive’s internal gearing was greased at the factory and should not need additional
grease until after 50 hours of operation or one year, whichever comes first. Follow the
greasing instructions below. Note that in some tightly packed engines you may need to
move internal components temporarily in order to access the gears.
1. To access the gear box, remove the cab from the chassis by unscrewing the
body mount screws (shown below) and lifting the cab from the chassis.
2. Once the cab is removed, remove the trucks by unscrewing the black Phillips
motor mount screw located on the underside of the drive trucks (shown below).
3. Once the motor mount screw has been removed, pull the motor away from the
truck block and lightly coat the motor worm gear and bronze drive gear
(in the truck block) with grease.

Cleaning The Wheels, Tires, and Track
Periodically check the locomotive wheels and
pickups for dirt and buildup, which can cause
poor electrical contact and traction and
prematurely wear out the neoprene traction tires.
Wheels and tires can be cleaned using denatured
(not rubbing) alcohol applied with a cotton swab.
To clean the track, use RailKing Track Cleaning
Fluid found in Maintenance Kit (30-50010) or
denatured (not rubbing) alcohol and a clean rag.
Unplug the transformer and wipe the rails of the
track, turning the rag frequently to ensure that
you are using clean cloth on the rails. Thereafter,
keep an eye on the track and clean it when it gets
dirty to ensure good electrical contact and to
lengthen the life of the tires.
Clean any type of track with this heavy-duty track
cleaning block ( . Durably constructed
from ABS plastic, the block includes a built-in
cleaning pad. For really stuborn track, you can
insert sandpaper into the block in just a few quick steps.

Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on each
powered truck block. While these tires are extremely durable, you may need to
replace them at some point. Please use the following instructions to replace the
traction tires.
1. Turn your engine upside down.
2. Remove the two Phillips screws that attach each truck side to the truck block.
3. Make sure the old tire has been completely removed from the groove in the drive
wheel, using a razor blade or small flathead screwdriver to pry away any remains.
4. Slip the new tire onto the wheel. You may find it useful to use two small
flathead screwdrivers to stretch the tire over the wheel.
5. If you twist the tire while stretching it over the wheel, you will need to remove
and reinstall the tire. Otherwise your engine will wobble while operating.
6. Make sure the tire is fully seated inside the groove. Use a razor blade to trim
away any excess tire that doesn’t seat itself inside the groove properly.
7. Reassemble in reverse order.
One set of replacement tires is packaged with the model. Additional tires are
available directly from the M.T.H. Parts Department (Order online: www.mth-

Battery Charger Port location.
Battery Location
Battery Charger Port
Self Charging Battery Back-up
The special rechargeable 2.4v self-charging battery recharges continuously during
train operation and should last for up to five years. The battery is a dry battery that
should not leak or cause any damage to your engine. Depending upon when your
engine was built, it may need to be charged right out of the box. If engine sounds
seem distorted or garbled at low voltages or become silent when power from the
transformer is turned off, test the battery to determine whether it should be
recharged or replaced.
Test: Put the engine in neutral and
leave the track voltage at 10-12 volts
(high enough for the lights to shine
brightly) for 15 minutes.
Recharge: If the sounds are
improved at the end of the 15-minute
test charge, the battery charge has run
down and can be recharged. There are
a number of ways you can do this:
•Leave the engine in neutral with track voltage at 10-12 volts for 6-7 hours so
the battery can fully recharge (if your engine has a smoke unit, be sure it is
turned off).
•Use M.T.H.'s battery recharger (Item No. 50-1019) (sold separately) that plugs
into a wall outlet and a special port under the engine to recharge the battery
overnight without leaving it on the track.
Replace: If the sounds are not improved at the end of the 15-minute test charge,
it is time to replace the battery. Available through M.T.H. Parts:
®
(Item No. 50-1024) AA NiCad Proto-Sound Battery (Blue Casing)
®
(Item No. BG4000004) AAA NiMH Proto-Sound Battery (Green Casing)
DO NOT substitute alkaline
batteries for these rechargeable
batteries. Using alkaline batteries in
this system can result in damamge
to the PS 2.0 circuit board and/or
the batteries.
**Do not use alkaline batteries for
testing or checking purposes for the
3-Volt PS2 boards. Using alkaline
batteries will damage the 3-Volt
battery charging circuit.**

Troubleshooting Proto-Sound 2.0 Problems
Although Proto-Sound® 2.0 has been designed and engineered for ease of use,
you may have some questions during initial operation. The following table
should answer most questions. If your problem cannot be resolved with this
table, contact M.T.H. for assistance (www.mth-railking.com, e-mail: parts@mth-
railking.com,Fax: [phone], Phone: [phone], Mail: 7020 Columbia

Starting Up
Bell
Remedy
Remedy
When I press the horn button, the bell comes on
instead.
I can't get any sound to play when I press the horn
button.
When I press the bell button, I get a station stop
announcement, not the bell. You are holding the bell button too long. Press it for only
about one second to trigger the bell.
That is normal for this model.
You may be pressing the button too quickly to trigger the
bell. Try pressing the horn button more slowly, taking
approximately one full second to fully depress the button.
Platform Action Sounds Remedy
Sometimes the Platform Action Sounds don't play. Platform Action Sounds play only in neutral at random
intervals.
Lock-out Remedy
I can't get the engine to run after I power up the
transformer. It sits still with the diesel and
compressor sounds running.
The engine won't lock into forward, neutral, or
reverse.
The engine is locked into the neutral position. Follow the
procedure in the "Lock into a Direction" section.
Engine speed must be below 10 scale mph (approx. 10
volts or less in conventional mode).
Volume Remedy
The sounds seem distorted, especially when the
bell is activated.
No Sound
Proto-Sound 2.0 volume is set too high. Turn the volume
control knob on the bottom of the chassis counter-
clockwise to reduce the volume.
Volume is set too low, adjust volume control knob on the
bottom of the chassis clockwise to increase the volume
or check connector to speaker.
Battery Remedy
The engine will not leave the initial neutral setting.
I get no sounds when the engine shifts between
directions.
After I turn off my transformer, my engine
continues to make sounds before quitting.
Check to be sure the battery is installed and fully charged.
See the "Self-Charging Battery Back-Up" section.
The battery may be dead or need to be charged. See the
"Self-Charging Battery Back-Up" section.
Proto-Sound 2.0 is designed to continue to sound for a
few seconds after power to the track has been shut off to
allow for a more realistic shut-down.
TAS Remedy
The TAS sounds occasionally repeat themselves. Proto-Sound 2.0 has a built-in random number generator
that randomly selects each sound clip to play. Because
there are a limited number of sound clips available in
each TAS sequence, it is probable that some of these
sound clips will be repeated from time to time.

Transformer Compatibility and Wiring Chart
Proto-Sound® 2.0 is designed to work with most standard AC transformers.
The chart below lists the many compatible transformers. Note that many of the
operational commands described in these instructions require a bell button, so if
your transformer does not have its own bell button, you should consider adding
one to get the full benefit of the system. In addition, the chart details how the
terminals on these transformers should be attached to your layout.

Additional Features Accessible With The DCS
Remote Control System
(Additional equipment required)
While conventional mode operation of a Proto-Sound 2.0 engine yields
wonderfully realistic sound and several train control features, command mode
operation allows the user to access a world of command functions never before
accessible to O Gauge railroaders. With the addition of the DCS Remote Control
System (including a DCS remote handheld and Track Interface Unit) users gain
many advanced features, including:
•DCS Proto-Speed Control - Establishes desired locomotive speed in
scale miles per hour increments via a thumbwheel control and allows
operator to set maximum speed and acceleration/deceleration rates
•ProtoSmoke™ Variable Output Control - Controls how much smoke
each engine outputs and matches smoke to locomotive speed
•Locomotive Lighting Control - Controls locomotive headlights, marker
and interior lights, beacon lights, ditch lights, and MARS lights
•Emergency Stop-Single button push stops all Proto-Sound 2.0 trains but
does not turn off the power
•One Touch Global Mute/UnMute-Single button mutes or unmutes all
DCS-controlled locomotives' user-defined actions, including sound, lights,
and smoke
•Proto-Dispatch Operation-Public Address-like feature allows users to
speak through locomotive speaker during operation
•Proto-Cast-Allows users to play audio recordings through locomotive
speaker during operation
•Proto-Doppler Sound Effects Set Up-Users can configure locomotive
for Doppler Operation, including setting distance points for Doppler
start, repeat, and stop modes
•Independent Volume Control of Engine Sounds, Bell, Horn & Whistle
for each Locomotive
•Control up to 50 different DCS-Equipped Locomotives at one time with
multiple TIUs
•Proto-Effects™ Set Up-User can select individual Proto-Effects™
operations to be active or inactive, including cab chatter, train wreck
sounds, coupler sounds, Direction Control Set Up-User can set initial
individual start-up direction (start in forward or reverse) for double-
