RailKing 4-Car Subway Set Operating Manual
RAILKING
QUICK START - BASIC OPERATION
The RailKing 4-Car Subway Set contains state-of-the art electronics with
several built-in automatic features for incredibly realistic operation. Despite
these advanced features, the 4-Car Subway Set is easy to operate with any
compatible standard AC transformer (see the compatibility chart on page
28).
All models are controlled by a ProtoSound® 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 throttle on the transformer
can be advanced. You will
see that only the powered
car’s lights come on and that only two dings of the ProtoSound bell occur
(on ProtoSound equipped 3-rail
models). The car does not run.
This is known as the RESET state
and is explained in more detail
beginning on Page 4. The
ProtoSound® DCRU® will not
power the motor until the throttle
is turned OFF and then ON again. At this point, the car will now function
just like any other engine equipped with an electronic or mechanical E-unit.
On ProtoSound-equipped cars, the motor sounds will change slightly in
volume as the car begins to move. The horn can be activated by pressing
the whistle button on the transformer just as any horn would be activated.
See the sections later in this guide, beginning on page 5, for more
information on activating the horn and bell sounds.
