EMD F40PH DIESEL
LOCOMOTIVE
OPERATING INSTRUCTIONS
Thank you for purchasing the MTH Electric Trains EMD F40PH diesel engine. This 1/4" scale
reproduction of the famous EMD roadhorse measures more than 15 inches in length and
weighs almost 5 pounds. Despite its scale size and intricate detailing, it can operate for years
on O-31 3-Rail track with any compatible standard AC transformer (see the chart on page 25)
and is completely compatible with most 3-rail locomotives, rolling stock and accessories. If you
purchased the 2-rail model, the engine should negotiate 36 inch radius curves and is
completely compatible with any DC power source.
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 Basic Operating
Instructions found on Pages 3 and 4 should be read so that you understand the basics of the
operating system. Those features marked for 2 and 3-rail are found in all model types.
Features not marked as such are only available in the 3-rail ProtoSound equipped models.
