PREMIER GP 7/9 DIESEL ENGINE
OPERATING INSTRUCTIONS
Thank you for purchasing the Premier® production of General Motors' GP
7/9 diesel engine. 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 31 for a list of compatible transformers) and is completely
compatible with most 3-rail locomotives, rolling stock and accessories.
The locomotive is equipped with 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
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
Proto sound® models and are marked as such. Features not marked as
Proto sound® features are available in all models.
