RAILKING F-3 AA SET
OPERATING INSTRUCTIONS
Thank you for purchasing the RailKing® F-3 AA Set. The engine’s
durable ABS body and die-cast trucks are traditionally sized for operation
on most O-31 Gauge track. The engine should operate for years with most
compatible AC transformers (see the chart on page 30 for a list of
compatible transformers) and is completely compatible with most 3-rail
locomotives, rolling stock and accessories.
The locomotive is equipped with either an electronic horn or the Proto-
Sound® Digital Sound and train control system which contains several
deluxe features that are simple and fun to operate. Each feature is described
among the following pages which should be read before the engine is
operated. For those of you who can’t wait to get started, the
Quick Start
Basic Operating Instructions
found on Page 3 should be read so that you
understand the basics of the operating system. Please note that some
features are only found in the Proto-Sound® models and are marked as
such. Features not marked as Proto-Sound® features are available in all
models.
