RailKing D&RG 4-6-0 Operating Manual
QUICK START - BASIC OPERATION
The RailKing D&RG 4-6-0 contains state-of-the art electronics with
several built-in automatic features for incredibly realistic operation. Despite
these advanced features, the D&RG 4-6-0 is easy to operate with any
compatible standard AC transformer (see the compatibility chart on page
34). All models are equipped with an operating smoke system that
should
be primed with smoke fluid before operating
. Adding 15 - 20 drops of
fluid through the smoke stack should be sufficient.
If you choose to not
prime the units
with fluid
,
turn the smoke unit switch located under the
trailing truck to the OFF position
. (See Figure 3 on page 4) This will
prevent any damage from occurring to the smoke unit when running the
engine without a primed smoke unit. For
more information see the section on page 4
on Smoke Unit operation.
The D&RG 4-6-0 model is controlled by a
Proto-Sound® 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. Before the engine can be
operated however, the reverse unit plug that extends out of the tender must
be inserted into the receptacle at the back of the boiler cab as seen in Figure
1. Once the plug is inserted, the throttle on the transformer can be
advanced. You will see that only the engine’s lights come on and that on
Proto-Sound® equipped engines, two dings from the sound system will
chime followed by the steam compressor pump sounds. The engine does
not run. This is known as the RESET state and is explained in more detail
beginning on Page 5. The Proto-Sound® 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.
