Set Up Checklist
Lubricate the locomotive
Prime the smoke unit
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” in
Fig. 1. Do not over-oil. Use only a drop or two on each pivot point.
Priming the Smoke Unit
When preparing to run this engine,
add 15-20 drops of smoke fluid
through the smokestack. 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 the fluid (or
have already added the fluid but
choose to run smoke-free), turn off
the smoke unit switch

Placing the Engine on Track
Your Premier Steam Engine is equipped with a tetherless drawbar. There is no
unsightly cable or box showing between the engine and tender to detract from the
appearance of the model. The electrical connections pass through conductors
within the drawbar, so it is important that the connector be properly inserted. The
connector is fixed to the rear end of the drawbar. The mating connector is attached
to a swivel connection on the front of the tender frame. The drawbar is connected
to the engine chassis with a screw and should not need any attention.
In order to mate the connectors of the drawbar and the tender, place the engine
and tender on the track. Then position the tender over the drawbar and insert the
drawbar pin into the hole in the drawbar. Now grasp the tender with both hands as
shown in Fig.3A and place a finger on each side of the drawbar near the connector.
With your fingers on the drawbar, push the drawbar connector up into place. The
connector will make a slight click when the connector is properly seated.
To disconnect the engine and tender apply downward until the connector
separates.
The drawbar is able to withstand a 90 twist, such as might be experienced in a
derailment and turnover of the engine or the tender.
If the drawbar connector is not properly seated when power is applied to the
engine, you may experience some of the following malfunctions.
- The lights do not light or only some lights light.
- The smoke unit does not function
- The engine will not move when the reverse unit is cycled.
If this happens, turn off the track power and make sure that the drawbar
connector is properly connected. Then reapply the track power.

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 before forward
each time the track voltage is turned off for 25
seconds or more.
Grade Crossing Signal DCS Mode Only - Customers that operate this engine in
DCS will find a new feature added to the engine sound set. Now there is a soft key
(SXS) that sounds the correct 2 longs, a short and another long whistle blast to
announce that the train is approaching a grade crossing.
To sound the grade crossing signal, locate the soft keys at the top of the DCS
Remote. Scroll to the left until SXS acronym is showing.
A single push and release of the SXS soft key will produce the correct 2 longs, a
short and another long whistle blast of the Grade Crossing Signal.
Anytime you want to sound the Grade crossing Signal just press and release the
SXS soft key.

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 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 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
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.

4-8-2 U1F Mountain Steam Locomotive
10
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 powered off for five seconds or more.

Maintenance
Lubricating and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
You should regularly lubricate all side rods, linkage components and
pickup rollers to prevent them from squeaking. Use light household
oil and follow the lubrication points marked “L” in Fig. 2.
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. To access the gear box and axles, do the following:
1. Turn the engine upside down.
2. Remove the Phillips screws (marked “GREASE”) located at each set of wheels
and under pick up rollers (Fig. 6).
3. Use a grease tube dispenser to put a small amount (approx. 1-2 ml.) of lithium-
based grease into the screw holes.
4. Replace the screws.

You should also grease the leading and trailing locomotive truck tongues to enhance
their ability to slide on the chassis. Follow the grease points shown on Fig. 6.
Cleaning the Wheels, Tire, Track
Periodically check the locomotive wheels and
pickups for dirt and buildup, which can cause
poor electrical contact and traction as well as
prematurely wear out the neoprene traction tires.
Wheels and tires can be cleaned using denatured
(not rubbing) alcohol applied with a cotton swab.

Traction Tire Replacement
Your locomotive is equipped with two neoprene rubber traction tires on the rear set
of flanged drivers. While these tires are extremely durable, you may need to replace
them at some point.
1. Remove the side rods from the wheels in order to slip the new tire over the
grooved drive wheel. Make sure to note the position of all rods before removing.
2. 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.
3. 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.
4. 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.
5. 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.
6. Reinstall the side rods in the same positions as noted. Failure to align rods may
cause binding or damage to the drive system.
One set of replacement tires is packaged with your model. Additional sets are
available directly from the M.T.H. Parts Department (phone: [phone]; e-mail:
[email protected]; mail: 7020 Columbia Gateway Drive, Columbia MD
21046-1532).
Headlight Replacement Instructions
The locomotive’s lights are controlled by a constant voltage circuit in the engine.
They are easy to remove and replace when they burn out. See the diagrams and
directions below for instructions on accessing and replacing the light bulbs in this
locomotive.
You can obtain replacement bulbs directly from the M.T.H. Parts Department
(order online: www.mth-railking.com, e-mail: [email protected]; mail: 7020

Self Charging Battery Back-Up
The two special AA size 1.5v NiCad self-charging batteries recharges continuously
during train operation and should last for up to five years. The batteries are dry
battery that should not leak or cause any damage to your engine. Depending upon
when your engine was built, they 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 batteries to determine whether
they 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 and the engine to move steadily) for 15
minutes.
Recharge: If the sounds are improved at the end of the 15-minute test charge,
the batteries 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 batteries 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 water hatch in the tender to recharge
the batteries 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 batteries. Available through M.T.H. Parts.
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.
**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.**

ProtoSmoke® Unit Operation
This Premier steam locomotive contains a self-powered 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 a
harmless 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. 13). 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 the fluid (or
have already added the fluid but choose
to run smoke-free), turn off the smoke
unit switch located under the water hatch
on the tender (see Fig. 14). Failure either
to add fluid to the unit or to turn it off may damage the smoke unit heating
element and/or wick 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.
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. To remove the smoke unit you will first have to
remove the boiler shell (by removing the body mounting screws shown in Fig. 6 on
pg. 13), board and bracket that block the smoke unit assembly from being accessed.

ProtoSmoke® Unit Operation
1. Unplug the two wiring harnesses from the board mounted to the inside of the
boiler and behind the smoke unit.
2. Remove the two screws securing the smoke unit inside the shell as seen in Fig. 16.
3. With the board free of the mounting screws, slide the assembly out of the boiler
as seen in Fig. 16.
4. Once the unit is freed, remove the inspection cover (Fig. 16). Inspect the wick; if
it is darkly discolored and hard, it should be replaced.
