M.T.H. RAILKING 4-6-0 Operating instructions
Your RailKing Ready-To-Run train set is complete with everything you need to get
your model railroad up and running. This set includes a 4-6-0 steam locomotive, three
freight cars, a transformer, a loop of RealTrax, the RailKing wireless infrared remote
control, and the infrared activated remote lock-on. M.T.H.’s exclusive RailWare
CD-ROM, which is included with this set, provides track layout software and other
information helpful to model railroaders.
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 mode 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. Please read all the
accompanying instructions carefully before setting up and operating your train set.

Set Up Checklist
• Assemble RealTrax
• Connect the transformer
• Lubricate the train
• Place the engine and cars on the track and couple them together
• Apply power to run as described in the Basic Operation section of
these instructions.
Assembling RealTrax®
Unlike other O Gauge track systems, each RealTrax section features a realistic
built-in roadbed base, solid nickel-silver track rails, and realistic railroad ties,
all designed to give you an authentic looking track system. The quick
connectors and built-in roadbed allow you to set up RealTrax anywhere,
including most carpeted surfaces, without the need for track nails or the worry
of carpet stains.
Each RealTrax segment has at least one knock-out tab in the roadbed (on either
end of the segment) that can be removed with a pair of pliers to reveal an
opening for the lock-on that is used to connect the transformer to the track (see
below). To assemble RealTrax, follow the instructions on the following page.

The Z-750® power supply included with this set provides an easy-to-use, safe
power source for AC-powered trains and accessories.
Plug the wire from the transformer into the remote lock-on’s center port, then
plug the transformer into the wall outlet. Insert two AA batteries (not
included) into the remote handheld.
Lubricating the Engine
You must lubricate the engine before operating it. Use a light household oil
and follow the lubrication points marked “L” in Fig. 10 on Page 14. Do not
over oil. Use only a drop or two on each

pivot point.
Priming the Smoke Unit
You should prime the smoke unit with smoke
fluid before operating. Add 15-20 drops of
smoke fluid from the included pipette
through the smokestack (see figure 4), then
gently blow into the stack to eliminate any air
bubbles in the fluid.

If you choose not to prime the unit
with fluid, turn the smoke unit switch
located under theengine to the OFF
position (see Figure 5). 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.

Remote Control
The RailKing Remote Control System included with this set uses wireless
infrared technology, much like a television remote control, to allow users
remote control of their trains from up to 15 feet away. The remote and lock-on
replace the control box found with M.T.H.’s Z-750 ® transformer, and they are
designed for use with moderately powered transformers such as this one. It is
compatible with most manufacturer’s engines.
Because the RailKing remote is an infrared line-of-sight remote, you must aim
it at the lock-on in order to send signals to the track. You need to rotate the
lock-on’s receiver lens so that it faces the direction you will most often signal
from (see Figure 7 below). The receiver lens can be repositioned later as
needed. The green LED atop the lock-on will come on, indicating the track is
receiving power. Subsequent pushes of any buttons on the remote will cause
the LED to blink, indicating it is receiving the signal.
Note: The RailKing Remote Control and Remote Lock-on will not
operate engines equipped with pre-1997 versions of Proto-Sound or with
Proto-One, Proto-Plus, Proto-Deluxe, aftermarket systems.

Basic Operation
Throttle up the power to your track. Give your train enough power so that
the head light shines brightly. Then put the engine into motion by firmly
pressing the Direction button on your remote once.
Operation Buttons
Use the operation buttons on your remote as described below.
• Throttle – To increase or decrease track voltage, and therefore train speed,
press the throttle control rocker switch. Pressing the top end of the throttle
will increase voltage and speed. Pressing the bottom end of the throttle will
decrease voltage and speed. The engine will maintain the speed you set after
you release the throttle until you press it again to change the voltage and
• 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.
• B ell - 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 your turn it on until you press and release the button again to
turn it off.
• Direction – Your train is programmed to start in neutral. To put the engine
into forward and then to change the direction of the train or to put it into
neutral, firmly press and release the Direction button on your remote. Just as
you must stop your car 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.
• E mergency Stop – To drop track voltage instantly to 0, firmly press the
Emergency Stop button. All trains on the track controlled by the remote will
stop until you reapply voltage.
RailKing 4-6-0 Fast Freight Steam Engine
Manual Volume Control – To adjust the volume of all sounds made by
this engine, turn the master volume control knob located under the tender
clockwise to increase the volume and counter-clockwise to decrease the
volume (see Fig. 9).

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
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 (½ second); you may need to practice your timing to make this work
Feature to Be Activated:

Button Code:
1 Bell, 2 Whistles
1 Bell, 3 Whistles
1 Whistle, 2 Bells (from Neutral only)
1 Whistle, 3 Bells
1 Whistle, 5 Bells (from Neutral only)
RailKing 4-6-0 Fast Freight Steam Engine
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 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 4-6-0 Fast Freight 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.
RailKing 4-6-0 Fast Freight Steam Engine
Proto-Coupler® Operation
This locomotive is equipped with a coil-wound Proto-Coupler for remote
uncoupling action. Because the Proto-Coupler is controlled through the
Proto-Sound 2.0 microprocessor, it does not require an uncoupling track
section or modification to your layout to function. Use the code listed below 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.
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 maintain a constant speed
when speed control is turned off, you need to adjust track voltage yourself.
When speed control is off, the volume will drop to allow for better low voltage
operation. Full volume is restored upon reactivation of speed control.
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 horn blasts will indicate that the engine has made the change.
Repeat the 1 whistle, 2 bells code to return it to the other state. 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.
RailKing 4-6-0 Fast Freight Steam Engine
Lock into a Directional State:
You can lock your engine into a directional state (forward, neutral, or reverse)
to prevent it from changing 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
speed (< 10 scale mph), and quickly but firmly press your remote’s Whistle
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
whistle, 3 bells code to return the engine to its normal state, 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 horn 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
• Cab Chatter plays 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.
RailKing 4-6-0 Fast Freight Steam Engine
Care of the Remote Control
Your RailKing Remote Control System should offer years of trouble-free
service. There are a few things you can do to ensure trouble-free operation:
• If your train responds inconsistently, replace old batteries with fresh ones.
Do not mix old and new batteries.
• Remove batteries before storing for extended periods.
• Do not drop the remote. It can damage the delicate electronics inside.
• Any attempt by anyone other than an authorized M.T.H. repair person to
open and repair the handheld transmitter or lock-on may result in damage and
the loss of warranty protection.
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 Fig. 10. Do not over oil. Use only
a drop or two on each pivot point.
Pick-Up Rollers
Lubricate (L)
Figure 10. Lubrication Points on the Locomotive
RailKing 4-6-0 Fast Freight 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. Unscrew the chassis screws as shown in Fig. 11 and remove the boiler.
2. Open the gear box by unscrewing the screws on the plate located in front of
the motor.
3. Use a grease tube dispenser to put a small amount of lithium-based grease
into the gearbox.
Reassemble the engine in reverse order.

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 a clean rag and denatured (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. Because the
manufacturing process leaves a coat on RealTrax, you should clean the rails
after the first 30 minutes of use (you may smell something burning during
initial use as the coat burns off; this is normal). 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 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.
These screws 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
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
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.
Replacement tires are available directly from the M.T.H. Parts Department.
RailKing 4-6-0 Fast Freight Steam Engine
ProtoSmoke ® Unit Operation
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 figure 4 on pg. 4). 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 the body (see
figure 5 on pg. 5). 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
Smoke Unit
Cover Screws
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 the boiler shell (Fig. 11,
pg. 15) then the smoke unit inspection cover from the
smoke unit’s body (see Fig. 12). After removing the
chassis and inspection cover screws, lift the inspection

Caboose Light Bulb Replacement
To replace the interior light bulbs, follow these steps and refer to the diagrams
on page 20.
1. To remove the shell from the chassis, remove the four mounting screws
located underneath the trucks. (Figure 14-1)
2. With the four screws removed, lower the chassis from the shell, taking care
not to pull the wires out. (Figure 14-2)
3. Separate the interior from the shell by removing the step platform from both
ends. In order to do this you need to loosen the Ladder from the Catwalk. You
must do this carefully so that you don't scratch the paint on the roof of the
caboose. First remove the ladder from the Catwalk by pulling the ladder
upward and outward. You can then remove the step platforms. (Figure 14-3)
4. With the step platforms removed you can then lower the interior from the
shell. (Figure 14-4)
5. Replace the bulbs by pushing the socket up from the bulb holder and pulling
the bulb from its socket. Remove the vertical bulb simply by pulling it from its
socket. Replace with a new bulb, and reverse the steps to reassemble the
caboose. (Figure 14-5)

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 traveling 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. 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
• 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 (as described below) 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 directions below). Contact the M.T.H. Parts
Department (phone: 410-381-2580; e-mail: parts@mth-railking.com; 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: 410-381-2580; fax:
410-423-0009; service@mth-railking.com, 7020 Columbia Gateway Drive,

Starting Up
When I first turn the power on, the
engine will not begin to run. I have to
turn the throttle off and then on again
to get the engine to operate.
This is normal behavior. To prevent
accidental high-speed start-ups, ProtoSound 2.0 is programmed to start up
in neutral anytime track power has
been turned off for several seconds.

Cab Chatter
Sometimes the Cab Chatter sounds
don’t play.
Cab Chatter plays only in neutral at
random intervals.
I can’t get the engine to run after I
power up the transformer. It sits still
with the engine sounds running.
The engine is locked into the neutral
position. Follow the procedure in the
“Lock into a Direction State” section.
The engine won’t lock into forward,
neutral, or reverse.
Engine speed must be below 10 scale
mph (approx. 10 volts or less in
conventional mode).
The sounds seem distorted, especially Proto-Sound 2.0 volume is set too
when the whistle or bell is activated.
high. Turn the volume control knob on
the bottom of the chassis counterclockwise to reduce the volume.
The engine will not leave the initial
neutral state.
Check to be sure the battery is
installed and fully charged. See the
“Self-Charging Battery Back-Up”

be charged. See the “Self-Charging
Battery Back-Up” section.
After I turn off my transformer, my
engine continues to make sounds
before quitting.
Proto-Sound 2.0 is designed to
continue to sound for a few seconds
after power to the track has been shut
The FYS sounds occasionally repeat
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 4-6-0 Fast Freight Steam Engine
Once in FYS, the engine doesn’t go
into reverse.
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.
When the FYS enters its last
sequence the bell automatically
comes on.
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
When FYS is enabled, pressing the
whistle and bell buttons has no effect. effects in each sequence, ProtoSound 2.0 takes control of these
sound effects until you exit FYS.
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.
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.
While this Ready-To-Run set is equipped with everything you need to operate
it, the design allows flexibility. The train will operate on any traditional O-31
or larger O Gauge track system, including the RealTrax included with this
set or traditional tubular track. It is also compatible with most standard AC
transformer, including the hobby transformer packaged with your set. (See
page 27 for a complete list of compatible transformers and wiring

Transformer Compatibility and Wiring Chart
Note that many of the operational commands described in these instructions
require a bell button, so if you are using a transformer other than the one
included in this set and your transformer does not have its own bell button, you
should consider adding one to get the full benefit of the system.
