RAILKING PA AA 

DIESEL ENGINE

OPERATING INSTRUCTIONS

This RailKing PA AA set boasts a detailed ABS body and operates on O-31 track. This
RailKing Diesel Engine contains state-of-the-art electronics with many built-in automatic 
features for incredibly realistic operation.  Despite these advanced features, the
locomotive is easy to operate with any compatible standard AC transformer (see the
compatibility chart on page 18), and is completely compatible with most other 3-rail
locomotives, rolling stock, and accessories.

This locomotive is equipped with Proto-Sound 2.0 with Digital Command System
(DCS).  This new system will allow you to operate your locomotive in Command mode
(when used with the DCS Remote Control System, sold separately) or Conventional
mode.  Conventional operating features are described in the following pages, while the

DCS operating features are covered in the set of operating instructions that
accompanies the DCS equipment.

  Conventional Mode operation of this locomotive is

much simpler than operation of original Proto-Sound engines.  For your own safety and
that of your equipment, please read the instructions before you operate this engine.
