Diesel “Work Train“ Train Set Operating Manual
RAILKING
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
