MTH GP-9 DIESEL ENGINE
OPERATING INSTRUCTIONS
Thank you for purchasing the MTH Electric Trains GP-9 diesel
locomotive. This ¼" scale reproduction of the famous GP-9 locomotive
measures over 14" in length and weighs almost 4 pounds. Despite its scale
size, the locomotive is capable of operating on O-31 3-rail track with any
compatible AC transformer, (see page 33 for a complete list of compatible
transformers and wiring instructions) and is completely compatible with
most other 3-rail locomotives, rolling stock and accessories.
The locomotive is equipped with 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 Operating Instructions, found on
