SDP40F illustration, 1970s.

This illustration presents a playful rendition of SDP40F locomotive No. 610 pulling a baggage car and coaches. The first locomotive built expressly for Amtrak, the SDP40F was a six axle diesel-electric unit that sported a 3,000 horsepower engine. It was manufactured in 1973 and 1974 by the General Motors Electro-Motive Division.

Since many passenger rail cars were still heated via steam, the SDP40F included two steam generators and a water tank. Within a decade, most of these locomotives were replaced with F40PH models that could operate more easily with the new and refurbished fleet of all-electric passenger cars. This illustration was likely commissioned for use in promotional materials.
