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 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. To
assemble RealTrax, follow the instructions below.

Connecting the Transformer
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 as shown.
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 pg. 11. 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
the engine tothe 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.
Coupling the Engine and Cars
Our couplers are designed for realistic
operation. Place the engine and cars on
the track and couple them together. If
the coupler is already closed, press down
on the small finger that extends from
under the right side of the coupler to open
the coupler knuckle and allow the couplers
to interlock as shown in Figure 6
.
Insert the reverse unit plug that extends
out of the tender into the receptacle at the
back of the engine. Connect the draw bar
between the engine and tender.
WARNING: DO NOT CONNECT
THIS ENGINE TO A TENDER FROM
ANOTHER ENGINE; IT MAY CAUSE
SERIOUSDAMAGE.
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.

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-500™and Z-750®transformers,
and they are designed for use with moderately powered transformers such as
these. It is compatible with virtually any 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. 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(see figure 7 on
pg. 6).
• 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 speed.
•
Horn/Whistle - To sound the horn, firmly press the Horn/Whistle button. The
horn will sound for as long as you continue to depress the button. It will stop
when you release the button.
• 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 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.

RailKing N&W J Steam Engine
Speed Control:
M.T.H. engines equipped with Loco-Sound 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. The engine will run more slowly
at a given throttle voltage when speed control is on than when it is off.
To turn speed control on and off,put the engine in neutral, then press the
remote’s Whistle button firmly but quickly one time then immediately press
the Bell button two times. 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.
Direction Lock:
You can lock your engine into a directional state (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
speed (< 10 scale mph), and quickly but firmly press your remote’s Whistle
button once followed immediately by three presses of the Bell button. 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.

Proto-Cast and Proto-Dispatch:
When used with the remote lock-on included in this set, Loco-Sound-equipped
engines gain Proto-Cast
™and Proto-Dispatch™features.
Proto-Cast:
This feature allows you to
play audio recordings through your
engine’s speakers. You must supply the
audio source (a small portable is
sufficient) and a male-to-male mini cable
(1/8” plug, like that used for the headset
with a portable CD/tape player) to connect
your audio source to the Remote
Lock-On. To use Proto-Cast, simply plug
the mini-cable into your audio source
(usually into the headphone jack) and into
the “Audio” port on the right side of the
remote lock-on and adjust the volume.
Proto-Dispatch:
This feature allows you
to broadcast your own voice through your
engine’s speakers. You must supply the microphone and a mini cable (1/8”
plug, like that used for the headset with a portable CD/tape player) to connect
your microphone to the Remote Lock-On. To use Proto-Dispatch, simply plug
the mini-cable into the microphone and into the “Mic” port on the left side of
the remote lock-on and speak into the microphone.
When these features are in use, the locomotive’s own sounds (engine sounds
and bells, whistles, and horns) will be muted so that only the sounds you
broadcast will be heard. Because these two features are voice activated, there
will be a 10-15 second delay after you stop speaking into the microphone or
turn off the stereo before the engine sounds resume. To stop using the feature
and return to normal operation, unplug the cable from the lock-on jack.
If using parallel tracks with multiple Loco-Sound-equipped engines,
Proto-Cast and Proto-Dispatch transmissions from one track may be picked up
by the other nearby engines.
If you experience popping and interference, try cleaning the track with
denatured alcohol as described in the “Cleaning the Wheels, Tires and Track”
section of this booklet.
Note: M.T.H. does not recommend using Proto-Cast and Proto-Dispatch
at the same time.
