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
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.
Lubricate Pick Up Roller Axles (L)
Lubricate All Wheel Axles (L)
Figure 1. Lubrication Points on the Locomotive
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 15.
RKS SD-9 Diesel Engine with PS-2
Priming the Smoke Unit
When preparing to run this engine, add 15-20 drops of smoke fluid through the
smokestack (see Figure 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 conrol 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.

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.
Cycle Phases

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.

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
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.
RKS SD-9 Diesel Engine with PS-2
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
! 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
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 de pletion will play, and the knuckle will be
= Coupler
RKS SD-9 Diesel Engine with PS-2
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 Hor n/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.

Figure 5. Body Removal Screw Locations
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 Figure 5).
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 6 below as a guide and add grease to the points marked.
Grease Idler Gear (G)
Figure 6. Greasing The Idler Gears
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 (40-1099). 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.
First, remove the truck sides from the truck block. To do this, turn your engine
upside down. If there are visible Phillips screw heads between the truck frame and
truck block (see Fig. 7), go to step A. If not, go to step B.
A. Remove the two Phillips screws that attach each truck side to the truck block.
B. Remove the trucks (see page 11) 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.
Truckside Screws
4. 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 g roove

Self Charging Battery Back-up
The special NiCad 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:
Battery Charger Port
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
DO NOT substitute alkaline batteries
for these NiCad batteries. Using
alkaline batteries in this system can
result in damage to the PS 2.0 circuit
board and/or the batteries.
Lift Out Battery
**Do not use alkaline batteries for
testing or checking purposes for the 3Volt PS2 boards. Using alkaline
batteries will damage the 3-Volt
battery charging circuit.**
RKS SD-9 Diesel Engine with PS-2
ProtoSmoke™ Unit Operation
This diesel locomotive contains a Proto-Sound 2.0 controlled smoke unit that
outputs smoke through the smokestack 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
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 Figure 7). 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.
Add Smoke Fluid
Figure 7. Filling The Smoke Unit
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 see Fig. 3 on page 4.
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 to the
“OFF” position, fully counter clockwise position, see Fig. 3 on page 4. 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.
RKS SD-9 Diesel Engine with PS-2
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 Figure 8). 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:

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 doubleheading operations
•Locomotive Consist Set-up-User can determine locomotive values for
consist make-ups, allowing multiple locomotives belonging to a consist to
operate together

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.
