Compatibility
Our designers have sized the engine to operate on any traditional 0-27
or larger O Gauge track system, including RiteTrax using any standard
AC transformer including the Z-750 transformer packaged in your set.
(See page 19 for a complete list of compatible transformers as well as
wiring instructions.) All RailKing products are compatible with most
other 3-rail locomotives, rolling stock, and accessories.
Equipment Options
Your ready-to-run set features a Diesel “Work Train“ Train locomotive
equipped with an operating headlight, electronic horn, and DCRU®
electronic reverse unit. All are simple and fun to operate. In addition
to the locomotive, your set should also include an oval of RiteTrax®
track (8 curved and 4 straight sections), a RiteTrax® lighted lock-on and
wire harness set (for connecting the track to the transformer) and a 75watt Z-750 transformer and controller.
You’ll find complete instructions for choosing and setting up options in
the following pages. If you don’t read through the entire manual before
starting to operate your equipment, be sure to check the Quick Start
Basic Operating Instructions, which will give you the basics of the
operating system.

Track and Power
Although MTH Electric Trains manufactures its own track and
transformers, you can run your locomotive on 0-27 or wider-radius O
gauge track wired to draw power from any of the standard compatible
AC transformers listed in the chart on page 19. Be sure your track is in
good condition—clean and securely connected—to keep the locomotive
running and to prevent derailments. If you intend to utilize the
RiteTrax® track sections included in the set, see the directions below.
Setting Up the RiteTrax® Oval
Unlike other O Gauge track systems, each RiteTrax® track section
features a realistic built-in roadbed base, solid nickel-silver track rails and
realistic railroad ties all
designed to give the owner
an authentic looking track
system. In addition, each
RiteTrax® track section
employs the use of quickconnect connectors instead
of track pins or railjoiners to
assemble the track sections
to one another. The quick
connectors and built-in base
allow RiteTrax® track
sections to be setup
anywhere, including some
carpeted surfaces without the need for track nails or the worry of carpet

Preparing the Locomotive & Cars For
Operation
Before you run your locomotive, you must oil the locomotive.
Lubrication
Before you run the locomotive, use a light household or hobby oil to
lubricate the gears and pick up rollers. Apply a small drop of oil (a
pinpoint oiler will help
place the right amount of
oil where you need it) to
each of the points
indicated by in the diagram
in figures 8. You may also
want to use either a
locomotive repair cradle or
an old towel folded over to
provide a protective bed
for the locomotive shell
while you’re working on it.

Because the locomotives’s internal gearing has been greased at the
factory, you shouldn’t need to add more grease until you have run the
locomotive for 50 hours or owned it for a year, whichever comes first.
See the section on lubrication, pages(s) 11-12, for detail.
Operating The Engine and Cars
Once the track has been assembled and the transformer wired to the
track lock-on, you are almost ready to begin running your new train set.
Place the engine and cars on the
track and couple each up to one
another. If the coupler is already
closed, pressing down on the
coupler armature will open the
coupler knuckle to allow the
couplers to interlock with one
another. Before turning on the
transformer, it is important to
understand the features of your new
train set.

Electronic Reverse Unit
The locomotive is controlled by a DCRU® electronic reverse unit. The
reverse unit operates in the same manner that all reverse units function
by using forward, neutral and
reverse states that are entered
each time the throttle is
turned on and off or by using
the transformer direction
switch (if so equipped).
The reverse unit is designed
to ignore dirty track, dead spots on switches or minor short circuits
without disrupting the engine operation, even at slow, prototypical
speeds. Once the engine is placed on the track, the transformer
throttle can be advanced. You will see that only the engine’s lights
come on but that the engine does not run. This is known as the RESET
state and is required when used with after-market MTH ProtoSound®
sound systems. The DCRU® will not power the motor until the

throttle is turned OFF and then ON again. At this point, the engine will
now function just like any other electronic or mechanical E-unit.
In addition to the DCRU® electronic reverse unit, your new train set
locomotive features an electronic horn that can be activated by
pressing the white Horn/Whistle button on your Z-750 transformer.
Any compatible transformer whistle or horn button will also activate the
horn in your new locomotive. Simply pressing the Horn/Whistle button
whenever the throttle is above the OFF setting should activate the horn.
If the horn doesn’t blow, increase the throttle setting and press the
button again. The horn will blow as long as the button is depressed.
Now, if you’ve lubricated the locomotive friction points as indicated
earlier, you’re almost ready to start running your train set.
Transformer Operation
The Z-750 provides the model railroad enthusiast with an easy to use,
safe power source for AC-powered trains and accessories. Set up is
quick and easy by following the setup diagram below.
Functions:

Starting to Roll
Advanced the transformer throttle. The locomotive's light will come on
but the engine will not move until you turn the throttle back OFF and
then ON again. The engine should now proceed in the forward
direction. At this point, advancing the throttle further will allow the
engine to pick up speed, reducing the throttle will slow the engine
down. Turning the throttle OFF and then back ON will park the engine
into neutral. Cycling the throttle OFF and then back ON again one
more time will allow the locomotive to enter reverse.
An alternative method to using the throttle to enter the next reverse
unit phase is to press the direction button. When depressed, the
transformer interrupts all power to the track as long as the button is
depressed. Releasing the button reapplies power to the track at
whatever voltage level the transformer throttle is set at.
Press the horn button, the horn should sound.
Note: Pressing the bell button will have no affect on your engine because your locomotive
is not equipped with a bell. Only locomotives equipped with full digital sound systems
(which feature engine sounds, horns, bells, air-release sound effects, squeaking brakes and
many other locomotive related sound effects) can utilize the bell button.
Special Reverse Unit Options
Locking Out The Reverse Unit Into One Full-Time
Direction
Your DCRU® electronic reverse unit locomotive may be locked out
into one of three positions;
forward, neutral or reverse.
Locking the engine into
one of these three positions
prevents the locomotive
from cycling through the
reverse unit phases and is
useful for operators
employing block signal
operations on their layout.
Once locked into a
position, turning the

throttle off and then on again will not allow the engine to enter the next
reverse unit phase and instead keeps the engine in the current locked
out phase.
To lock out the engine into one of the three positions, simply enter that
position using the transformer throttle or direction button. Once in the
desired direction, remove the locomotive from the track and slide the
ON/OFF switch located on the bottom of the chassis (See Figure 11) to
the OFF position. This locks the engine into the desired direction.
Sliding the switch back to the ON position resets the DCRU® reverse
unit into its normal reverse unit cycling phases.
Note: Once the DCRU® reverse unit is locked out and an hour or more of non-use has
passed, the reverse unit may cycle into any of the three directional states. Should this occur,
the ON/OFF switch should be reset to the ON position to regain normal operation. If the
operator desires to lock the engine out in another direction state, repeat the above steps to
do so.
Using the Z-750 With Self-Recharging, Battery
Equipped After-Market Sound Systems
When using the Z-750 transformer with after-market digital sound systems
employing a self-recharging battery backup system, operators should be
aware MTH does not recommend leaving the engine in neutral with the
power on and the throttle above the setting shown in Figure 10 for an
extended period of time. If you are recharging the battery found in these
after-market sound systems with a Z-750 transformer while in the neutral
position, MTH recommends the throttle be positioned as shown in Figure
10 for optimum charging power.

Train Set Maintenance Instructions
Proper locomotive performance requires regular attention to
lubrication. The following guidelines should be followed to ensure that
your set’s locomotive last for many years.
Oil
Before operating the locomotive, apply a small drop of oil to lubricate
the gears and pick up rollers. Use light household oil and apply
sparingly only to the points indicated by Figure 8 on page 6. Wipe
away any excess, especially if oil spills onto the finish of the locomotive.
Figure 12: Removing the Diesel Work Train locomotive shell from the chassis.
To prevent accidental
scratches or other damage
to the locomotive shell
while you are working,
you may want to place the
locomotive in a repair
cradle or an old towel or
other cloth folded to
provide a firm but soft
resting place.
Check the locomotive
oiling points periodically
to be sure they are
moving freely and quietly.
If they are not, apply small

amount of oil again. Also check locomotive wheels for dirt build up
that can cause performance problems. Such dirt build up can interfere
with electrical contacts, reduce traction (especially on elevated track
sections), and cause neprene traction tires to wear out prematurely.
Grease
Your locomotive's internal
gearing has been greased at the
factory an should not need
additional grease until you have
run the locomotive for over 50
hours or owned it for a year,
whichever comes first.
Grease
Add grease by inserting it into
the gear box inside the
locomotive chassis. To reach
the gear box, remove the cab
from the chassis by unscrewing
the four chassis screws as
indicated in Figure 13 on page
11. Once you have removed the cab, remove the truck mounting
screws holding the truck to the motor. After removing this motor
mount screw, lift the motor away from the truck and use a grease tube
dispenser to coat the bronze drive gear inside the truck and the motor
worm gear on the motor. Reinsert the motor down into the truck and
reinstall the motor mount screws. Then fit the cab back in place and
reinsert the four chassis screws.

Locomotive Lamp Replacement
Your locomotive and
Superliner cars may
occasionally burn out their
headlights and/or interior
lights. Should this occur, you
will need to remove the body
from the chassis in order to
replace the burned out bulb.

To remove the Diesel “Work Train“ cab from its chassis, follow the
body removal instructions on the previous pages. Once the body has
been removed, push the headlight bulb downward and rotate it
counter- clockwise as seen in Figure 15 to remove the burned out bulb.
Caboose Car Lamp Replacement
To remove a passenger car body from its chassis, turn the car over and
locate and remove the two mounting screws (as seen in Figure 16)
attaching the roof to the body and chassis. Once the screws are
removed, gently lift the car roof up and away from the body and chassis
(see Figure 17).
After removing the roof from the body and chassis, locate the car
interior lamp housings mounted on the inside of the car body. Once

the lamp housing has been located, remove the burned out interior
bulb by pushing down and turning the bulb as indicated in Figure 17.
To replace the bulb, simply insert the replacement bulb into the empty
lamp housing and reattach the body to the chassis.
Locomotive Traction Tire Replacement Instructions
Your locomotive is equipped with four neoprene rubber traction tires
(two on each power truck). While these tires are extremely durable
and long-lasting there may arise a time where they will need to be
replaced. Should this occur, you will need to remove the trucks from
the chassis in order to slip the new tire over the grooved drive wheel.
Follow the lubrication instructions on the previous pages for removing
the trucks from the chassis. Once the trucks have been removed, you
will need to remove the trucksides in order to gain free access to the
wheels and the rubber traction tire grooves. See Figure 18 to remove
the trucksides.
Before the new tire can
be installed, you must
make sure the old tire
has been completely
removed from the
groove in the drive
wheel. Use a razor
blade or small flatblade
screwdriver pry away
any remains left from the
old tire that may still be
in the drive wheel
groove. Once the old
tire has been completely
removed, slip the new
tire onto the wheel. You
may find it useful to use
two small flatblade
screwdrivers to assist you in stretching the tire over the wheel. Be
careful to avoid twisting the tire when stretching it over the wheel. If a
twist occurs, the tire will have to be removed and reinstalled or a

noticeable wobble in your engine will occur when operating the
locomotive. In addition, it is important to make sure that the tire is
fully seated inside the groove. Any portion of the tire extending out of
the groove can cause the engine to wobble. A razor blade can be used
to trim away any excess tire that doesn't t seat itself inside the groove
properly.
Replacement tires are available directly from MTH Electric Trains.
