RAILKING 0-8-0 SWITCHER
STEAMENGINE
OPERATING INSTRUCTIONS
This RailKing 0-8-0 Switcher Steam Engine is produced in detailed Die-Cast Metal and
operates on O-31 track.
This RailKing Steam Engine contains state-of-the-art electronics
with many built-in automatic features for incredibly realistic operation. Despite these
advanced features, the locomotive is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page
21), and is completely compatible with
most other 3-rail locomotives, rolling stock, and accessories.
This locomotive is equipped with Proto-Sound 2.0 with Digital Command System
(DCS). This new system will allow you to operate your locomotive in Command mode
(when used with the DCS Remote Control System, sold separately) or Conventional
mode. Conventional operating features are described in the following pages, while the
DCS operating features are covered in the set of operating instructions that
accompanies the DCS equipment.
Conventional Mode operation of this locomotive is
much simpler than operation of original Proto-Sound engines. For your own safety and
that of your equipment, please read the instructions before you operate this engine.

RailKing 0-8-0 Switcher Steam Engine
Set Up
There are a few simple steps you must take before operating this RailKing
steamer.
1. You should prime the operating smoke unit with smoke fluid before
operating. Add 15-20 drops of smoke fluid through the smokestack, then
gently blow into the stack to eliminate any air bubbles in the fluid. See Fig.
5
on pg. 13.
2. If you choose not to prime the unit with fluid, turn the smoke unit switch
located under the tender to the OFF position (see Fig. 6, pg. 13).
Running the
engine without a primed smoke unit may cause damage.
See the
“ProtoSmoke Unit Operation” section of this book for more information on
smoke unit maintenance.
3. You should lubricate all side rods and linkage components and pickup
rollers to prevent them from squeaking. Lightly the drive gears (refer to page
11) to prevent them from squeaking. Use light household oil and follow the
lubrication points marked “L” in Figures 2 and 3
on pg. 10 . Do not over-oil.
Use only a drop or two on each pivot point.
4. Put your engine on the track and insert the reverse unit plug that extends out
of the tender into the receptacle at the back of the engine.
WARNING: DO
NOT CONNECT THIS ENGINE TO A TENDER FROM ANOTHER
ENGINE; IT MAY CAUSE SERIOUS DAMAGE.
Look at the bottom of
the engine and tender where each will have a color-coded stamp. If they match
you may connect those two pieces; if not, don’t.
5. Connect the draw bar between the engine and tender. If there are two holes
in the draw bar, the hole located farthest from the tender is for the minimum
track operation, such as O-31 circles of track. The second hole is for O-72 or
larger operation.
At this point, you are ready to begin running your engine.

RailKing 0-8-0 Switcher Steam Engine
Basic Operation
Throttle – Throttle up the power to your track. Give about 10-12 volts or
enough power so that the engine’s headlight shines brightly. Then put the
engine into motion by either firmly pressing the Direction button on your
transformer or remote once or dropping and advancing the throttle to put the
engine in forward.
Operation Buttons
Use the operation buttons on your transformer as described below.
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. The whistle has four different endings,
depending on whether you hold the button for less than three seconds, three
seconds, four seconds, or five seconds or longer.
Bell - To sound the 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.
Direction – Your train is programmed to start in neutral. The first direction
after neutral upon start-up is forward. Firmly press and release the Direction
button to allow the engine to move forward. Just as you must stop your
automobile between forward and reverse, this engine will not go directly from
forward to reverse; it goes into neutral between directions. If the train has been
moving forward, the first press of the Direction button will put the train from
forward into neutral, the second press into reverse, the third press back into
neutral, and the fourth back into forward. To prevent accidental high-speed
start-ups, this engine is programmed to restart in neutral each time the track
voltage is turned off for 25 seconds or more.
Volume Control –To adjust the volume of all sounds made by this engine,
turn the master volume control knob located under theengine clockwise to
increase the volume and counter-clockwise to decrease the volume (see Fig. 1).

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.
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
the reset state 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.
Activating Proto-Sound 2.0 Conventional Mode Features:
Proto-Sound 2.0 features are activated by sequences of Bell and 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 press the buttons for a shorter
time (1/2 second); you may need to practice your timing to make this work
smoothly.

Freight Yard Sounds (FYS):
Your engine is equipped with a sound package of freight yard sounds that you
can play when you pull into a yard. 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 sufficient time to run through each sequence.
1. To cue the sound system to play the FYS, quickly but firmly press the Bell
button once followed by 2 quick presses of the Whistle button while the engine
is moving.
2. Press the Direction button or drop and advance the throttle once to stop the
engine. This will trigger the first sequence of FYS. 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 Whistle and Bell buttons until the full FYS sequence is complete.
3. After waiting about 30 seconds for that sequence to run, press the Direction
button again to trigger the second sequence of FYS.
4. After about 30 seconds, press the Direction button again to trigger the third
FYS sequence.
5. 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 sequence.
The FYS 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.

RailKing 0-8-0 Switcher Steam Engine
Tips on Using FYS
• You can terminate FYS at anytime by turning off power to the
track for 15 seconds.
• You do not have to be in Forward to use FYS. 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 even if you are double-heading with another
engine. If the second engine is not equipped with FYS at all, you
must remember not to leave the throttle at a high voltage level
once you have stopped the engine to run the FYS. Otherwise, the
engine without FYS will begin vibrating on the track as its motors
strain to move the train, since they cannot be automatically
disabled during the FYS cycle. If the second engine is an original
Proto-Sound engine equipped with FYS, you may choose to
disable it when used in double-heading operations, so you will not
experience competing FYS sounds. To disable FYS in an original
Proto-Sound engine, see the operating instructions for that engine.
• FYS can be triggered from Neutral. It will operate the same as if
triggered while in motion except that, at the conclusion of the
FYS, 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 two 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 p.
5) to fire the coupler.
Rear Coupler:
To fire the rear coupler, press the Bell button once followed immediately by
three pushes of the Whistle button. The sound of the liftbar and air line
depletion will play, and the knuckle will be released.
Front Coupler:
To fire the front coupler, press the Bell button once followed immediately by
four pushes of the Whistle button. 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.
To turn speed control on and off, put the engine in neutral, then press the
transformer’s Whistle button one time then immediately press the Bell button
two times. Two whistle blasts will indicate that the engine has made the
change. 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.
Note: When speed control is turned off, the Proto-Sound 2.0 system will limit
the volume in order to operate more smoothly at lower voltages. Full volume
is restored upon reactivating speed control.

9
RailKing 0-8-0 Switcher Steam Engine
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 press the Horn
button once followed immediately by three presses of the Bell button.
Two
horn 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,
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 press the Whistle button once, followed
immediately by five quick pushes of the Bell button.
Two 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.

Lubrication and Greasing Instructions
The engine should be oiled and greased in order to run properly.
You should regularly lubricate all side rods and linkage components and
pickup rollers to prevent them from squeaking. Use light household oil and
follow the lubrication points marked “L” in Figures2 and 3. Do not over oil.
Use only a drop or two on each pivot point.

RailKing 0-8-0 Switcher Steam Engine
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, do the following:
1. Turn the engine upside down.
2. Remove the Phillips screw (marked “GREASE”) located at the third set of
drivers (counting from the front of the engine).
3. Use a grease tube dispenser to put a small amount (approx. 1-2 ml.) of
lithium-based grease into the gearbox.
4. Replace the screw.

RailKing 0-8-0 Switcher Steam Engine
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
alcohol (not rubbing alcohol), which can be found in home improvement
stores, applied with a cotton swab.
Occasional cleaning of the track will also help to ensure good electrical
contact and to prolong the life of your engine’s tires. To clean the track, use a
clean rag and denatured alcohol (not rubbing alcohol). 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.
Traction Tire Replacement Instructions
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 (the rods that connect each drive wheel to the other)
from the wheels in order to slip the new tire over the grooved drive wheel.
This screw can be loosened with a 5mm nutdriver.
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.
One set of replacement tires is included with the model. Additional tires are
available directly from the M.T.H. Parts Department (phone: [phone];
fax: [phone]; e-mail: [email protected]; mail: 7020 Columbia
Gateway Drive, Columbia MD 21046-1532).

ProtoSmoke®Unit Maintenance
This steam locomotive contains a smoke unit that outputs smoke through the
smokestack on the boiler 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.
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. 5). We recommend M.T.H.
ProtoSmoke, Seuthe, LGB, or LVTS fluids (a
small pipette of ProtoSmoke fluid is included).
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 thetender body (see Fig. 6).
Failure either to add fluid to the 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.
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. Remove boiler from chassis using screws shown
in Fig. 4. Remove screws for smoke unit mounting bracket (Fig. 7), then
remove smoke unit inspection cover screws (Fig. 8). Remove the smoke unit

Self-Charging Battery Back-Up
The special NiCad 7-cell 8.4v self-charging battery in this engine improves
performance at any speed. It ensures that power to the sound system will
remain on during directional changes, or when travelling over dirty track or
switches. The self-charging battery system is automatically turned on or off
whenever track power is turned on or off.
Track power (when applied) recharges the battery, which should last for up to
five years, and the special NiCad battery is a dry battery that should not leak or
cause any damage to your engine. However, even this special battery will
eventually wear down and need to be replaced. When you notice that your
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.
• Put the engine in neutral and leave the track voltage at 12 volts for 15
minutes
• If the garbled or distorted sounds are reduced, the battery charge has run
down and can be recharged. Do this by leaving the engine in neutral with track
voltage at 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). Or you can remove the
battery(see instructions on pg. 17, figure 11)and charge it in any standard
slow charge battery recharger, following the recharger’s directions.
• If the sounds are not improved at the end of the 15 minute test charge, it is
time to replace the battery (see instructions on pg. 17, figure 11). Contact the
M.T.H. Parts Department (phone: [phone]; e-mail:
[email protected]; mail: 7020 Columbia Gateway Drive, Columbia MD
21046-1532) for a replacement battery. 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
like those found in most convenience stores.

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 (telephone: [phone]; fax:
410-423-0009; e-mail: [email protected], mail: 7020 Columbia

Remedy
Sometimes the Cab Chatter sounds
don’t play.
I can’t get the engine to run after I
power up the transformer. It sits still
with the engine sounds running.
The engine won’t lock into forward,
neutral, or reverse.
The sounds seem distorted, especially
when the whistle or bell is activated.
The engine will not leave the initial
neutral setting.
The FYS sounds occasionally repeat
themselves.
I get no sounds when the engine shifts
between directions.
After I turn off my transformer, my
engine continues to make sounds
before quitting.
Cab Chatter plays only in neutral at
random intervals.
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).
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.
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.
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.

RailKing 0-8-0 Switcher Steam Engine
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 rings of the bell,
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.
Compatibility
This engine will operate on any traditional O-31 or larger O Gauge track
system, including M.T.H.’s RealTrax®or ScaleTrax™or traditional tubular
track. It is also compatible with most standard AC transformers. (See page 21
for a complete list of compatible transformers and wiring instructions.)
