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” in
Fig. 1. 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 (see Fig. 2). We recommend M.T.H. ProtoSmoke, Seuthe, LGB, or
LVTS fluids. 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 switch to the
“OFF” position. 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.

Basic Operation
The Throttle knob controls how fast your train will travel. Turn the throttle knob
up ½-way, until the engine and caboose 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 whistle, firmly press the Horn/Whistle button. The
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 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 StationAnnouncements (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

!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 Whistle buttons and can ring the bell or blow the
whistle as usual.
Tips on Using FYS/PSA
!You can terminate FYS/PSAat 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/PSAeven 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
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 8) 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 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
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 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
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 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 as seen in Figure 5 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 Fig. 6b).
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.

5. After repeating the procedure for the other motor, reassemble the chassis and
body, being careful that the wire harnesses are not caught between the chassis and
body, and reinstall the body mount screws.
Lubricate the outside truck block idler and drive gears with grease. Use the
diagram shown in Figure 6b below as a guide and add grease to the points marked.
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 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.

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, they may
occasionally need replacement.
First, remove the truck sides from the truck block. To do this, turn your engine
upside down and remove the chassis as detailed on page 12.
Remove the trucks from the chassis and the truck sides from the trucks in order to
slip the new tire over the grooved drive wheel. Once the truck sides have been
removed:
1. 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.
2. 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. 3. 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. 4. Make sure the tire is fully
seated inside the groove. Use a razor blade to trim away any excess tire that will
not seat inside the groove properly.
5. Reassemble in the reverse order.
Replacement parts are available directly from the M.T.H. Parts Department (order

Locomotive Light Bulb Replacement
To replace the headlight and cab interior lights on this locomotive, follow these
instructions.
Follow the cab removal instructions in the “Lubrication and Greasing
Instructions” section on pg. 12 of this manual. Once the body has been removed,
follow the instructions below and remove the lights as shown in Fig. 7.
Headlight
The locomotive’s headlight is controlled by a constant voltage circuit in the engine.
The headlight is easy to remove and replace when it burns out. The bulb has a
quick disconnect plug that attaches the bulb harness to a connector terminal.
To replace the headlights mounted to the inside of the shell, remove the wires
from the wire clips and unplug from the spring contact bracket. Gently disconnect
the bulb harness from the connector terminal and remove bulbs through the rear
of the headlight socket. Insert the new bulb harness and reconnect. Replacement
bulb harnesses are available directly from the M.T.H. Parts Department.
Cab Interior Lights
The cab interior lights are also made with a bulb harness that attaches to a quick
disconnect plug. Gently disconnect the bulb harness from the connector, and
remove the bulb. Insert the new bulb harness and reconnect. Replacement bulb
harnesses are available directly from the M.T.H. Parts Department.

Self-Charging Battery Back-up
The special NiCad 7-cell 8.4v 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 (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. A standard 9v
alkaline battery can be substituted until your replacement arrives, but since alkaline
batteries cannot be recharged, it will eventually wear down. Do NOT use a 6-cell
7.2v 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 a 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 (see Fig.8). We recommend M.T.H. ProtoSmoke, Seuthe, LGB, or
LVTS fluids. 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 (se Fig. 3)
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 switch to
the “OFF” position (see Fig. 3). 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.
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.
AC6000 Diesel Engine Proto-Sound®2.0
17
Figure 8. Filling The Smoke Unit
Add Smoke Fluid
Through Smokestack

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
(See Figure 5), remove the smoke unit inspection cover (see Fig. 9). 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:

Proto-Sound 2.0 is designed to
continue to sound for a few
seconds after power to the track
has been shut off.
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 FYS sequence, it
is probable that some of these
sound clips will be repeated from
time to time.

FYS Remedy
Once in FYS, the engine doesn’t
go into reverse.
When the FYS enters its last
sequence the bell automatically
comes on.
When FYS is enabled, pressing
the whistle and bell buttons has no
effect.
I push the direction button but the
next sound clip in the sequence
does not play or the engine does
not come out of FYS after fourth
press of the direction button.
So that FYS effects can be as
realistic as possible, Proto-
Sound 2.0 disables the
reversing unit whenever FYS is
enabled. This way the engine
remains still at its stop as the
operator cycles through the
FYS sequences.
FYS is programmed to start
ringing the bell at that point. After
approximately 12 seconds it will
automatically turn off.
Because FYS must control various
effects in each sequence, Proto-
Sound 2.0 takes control of these
sound effects until you exit FYS.
Each FYS clip must play for
approx. 30 seconds before FYS
will advance to the next step in the
FYS cycle. Wait at least 30
seconds in each FYS sound clip
before pressing the direction
button.
