RAILKING SD-90 MAC

OPERATING INSTRUCTIONS

Thank you for purchasing the RailKing® production of EMD's SD-90

MAC diesel engine. The engine's durable ABS body and die-cast trucks

are traditionally sized for operation on any O-31 Gauge track. The engine

should operate for years with any compatible AC transformer (see the chart

on page 35 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

ProtoSound® 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 Pages 3 and 4 should be read so that

you understand the basics of the operating system. Please note that some

features are only found in the ProtoSound® models and are marked as such.

Features not marked as ProtoSound® features are available in all models.
