USRA 2-8-8-2 Steam Engine Operating Instructions
QUICK START - BASIC OPERATION
The RailKing USRA 2-8-8-2 contains state-of-the art electronics with
several built-in automatic features for incredibly realistic operation. Despite
these advanced features, the USRA 2-8-8-2 is easy to operate with any
compatible standard AC transformer (see the compatibility chart on page
31). 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) 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 USRA 2-8-8-2 model is controlled by
an electronic reverse unit (in mechanical
whistle equipped engines) or by the
Proto-Sound® Digital Sound and Train
Control System (in Proto-Sound® equipped
engines). In either model, 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 Proto-Sound® 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 6. The ProtoSound®
electronics 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.
