Set Up Checklist
- Lubricate the locomotive
- Check to see whether the battery needs to be charged for full sound effects
- Prime the smoke unit
- 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 16.

Priming the Smoke Unit
When preparing to run this engine, add 15-20 drops of smoke fluid through the
smokestack (shown below). We recommend M.T.H. ProtoSmoke™ fluid. Do not
overfill the unit or the fluid may leak out and coat the interior engine components.
If you choose not to add smoke fluid (or have already added fluid but choose to
run smoke-free), turn off the smoke unit by turning the smoke unit control fully
counter clockwise. Failure either to add fluid to the smoke unit or to turn it
off may damage the smoke unit heating element and/or wicking material.

Ensuring Proper Power to Track Polarity
Changing Track Polarity Inside the Locomotive
For 2-rail DCS operation, it is important that the polarity from the transformer to
the engine is properly configured. Correct polarity can be accomplished by
ensuring that the wiring from the TIU to the track and orientation of the
locomotive when sitting on the track follows the illustration below.
To TIU Black Terminal
To TIU Red Terminal
Failing to properly configure the polarity for 2-rail operations will result in the
locomotive starting in reverse instead of forward or not receiving the DCS signal.
Should this occur, it is not necessary to swap the wires from the transformer to
the track or reverse the locomotive’s orientation on the track itself. Instead,
simply slide the polarity switch shown below in the opposite direction. For the
configuration and polarity shown above the DCS Polarity switch should be
towards the front of the locomotive.

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:
Proto-Sound® 2.0 features are activated by sequences of Bell and Horn/Whistle 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/ whistle or ring the bell,
you should tap the buttons very quickly with a ½-second pause between button presses.
You may need to practice your timing to make this work smoothly.
Freight Yard Sounds (FYS) or
Passenger Station Announcements (PSA):
Your engine is equipped with a sound package of either freight yard or passenger station
sounds that you can play. Each sequence described below will play as long as it is left
on, randomly generating sounds, but be sure to allow approximately 30 seconds
between the button pushes described below to allow the FYS/PSA sufficient time to
run through each sequence.
!To cue the sound system to play the FYS/PSA, quickly but firmly tap the Bell button once
followed by 2 quick taps of the Horn/Whistle button while the engine is moving. Tap the
buttons quickly but allow approximately ½ second between each press.
!Press the Direction button once to stop the engine. This will trigger the first sequence of
FYS/PSA. The reverse unit is temporarily disabled so that the train will not move as you
use the Direction button to trigger the sounds, and Proto-Sound® 2.0 has disabled
operator control over the Horn/Whistle and Bell buttons until the full FYS/PSA sequence
is complete.
!After waiting about 30 seconds for that sequence to run, press the Direction button again
to trigger the second sequence of FYS/PSA.
!After about 30 seconds, press the Direction button again to trigger the third FYS/PSA
sequence.
!Again, after allowing about 30 seconds for that sequence to run, press the Direction button
one more time to trigger the fourth and final FYS/PSA sequence.

!The FYS/PSA will continue, and within a few seconds, the engine will start and move out
on its own at the current throttle setting, in the same direction it was traveling when you
began the sequence. Once the bell turns off, the operator regains control of the
transformer's Bell and Horn/Whistle buttons and can ring the bell or blow the
horn/whistle as usual.
Tips on Using FYS/PSA
!You can terminate FYS/PSA at any time by turning off power to the track for 15
seconds.
!You do not have to be in Forward to use FYS/PSA. At the conclusion of the full
sequence, the train will pull away from the station in whatever direction you were
going when you activated the feature.
!You can use FYS/PSA even if you are double-heading with another engine. If the
second engine is not equipped with Proto-Sound® 2.0, you must remember not
to leave the throttle at a high voltage level once you have stopped the engine to
run the FYS/PSA. Otherwise, the engine without FYS/PSA will begin vibrating
on the track as its motors strain to move the train, since they cannot be
automatically disabled during the FYS/PSA cycle (or if an original Proto-Sound
engine, FYS/PSA are triggered differently and that engine's motor-disable feature
will not be active when you run FYS/PSA in Proto-Sound® 2.0).
!FYS/PSA can be triggered from Neutral. It will operate the same as if triggered while
in motion except that, at the conclusion of the FYS/PSA, the engine will depart
in the next direction of travel, as opposed to the direction it was traveling before
entering Neutral.
Proto-Coupler™Operation (Hi-Rail Version Only)
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 (and in the chart on page 7) 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.

Reset to Factory Defaults:
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.
Automatic Sounds:
Certain Proto-Sound® 2.0 sound effects automatically play in programmed conventional
mode conditions:
!Squealing Brakes play any time the engine's speed decreases rapidly.
!Cab Chatter plays at random intervals when the engine idles in neutral.
!Engine Start-up and Shut-down sounds play when the engine is initially powered on or is

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 as seen in photo 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 (see above).
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.
4. Reassemble the truck and motor, being careful not to pinch any wires between
the truck block and motor mount.

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 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

ProtoSmoke™Unit Operation
This diesel locomotive contains a Proto-Sound® 2.0 controlled smoke unit that
outputs smoke through the smkestack on the roof of the engine. The smoke unit
is essentially a small heating element and wick that soaks up and then heats a
mineral oil-based fluid that emits smoke. The smoke is then forced out of the
stack by a small electric fan. Smoke volume is controlled by the Proto-Sound 2.0
system.
With a few easy maintenance steps, you should enjoy trouble-free smoke unit
operation for years.
When preparing to run this engine, add 15-20 drops of smoke fluid through the
smokestack (shown below). We recommend M.T.H. ProtoSmoke™ fluid. Do not
overfill the unit or the fluid may leak out and coat the interior engine components.
To adjust the amount of smoke produced, turn the smoke unit volume control
clockwise to increase the amount of smoke, or counter-clockwise to reduce the
amount (shown below)
If you choose not to add smoke fluid (or
have already added fluid but choose to run
run smoke-free), turn off the smoke unit
by turning the smoke unit control fully
counter clockwise. Failure either to add
fluid to the smoke unit or to turn it off
may damage the smoke unit heating
element and/or wicking material.

Inspecting the Smoke Unit Wick
Inspection Cover Screws
When the smoke output while running the engine begins to diminish, add another
10-15 drops of smoke fluid or turn the smoke unit off.
When storing the unit for long periods of time, you may want to add about 15
drops of fluid to prevent the wick from drying out.
After removing the engine from storage, add another 25 drops of fluid, letting the
wick soak up the fluid for 15 minutes prior to operation.
If you experience poor or no smoke output when the smoke unit is on and has
fluid, check the wick to see if it has become hard, blackened, and unabsorbent
around the heating element. After removing the locomotive body from its chassis,
remove the smoke unit inspection cover (shown below). After removing the
inspection cover screws, lift the inspection plate away and inspect the wick. If it is
darkly discolored and hard, it should be replaced.
Replacement parts and wick replacement instructions are available directly from
the M.T.H. Parts Department (Order online: www.mth-railking.com, e-mail:
