EMD E8

The EMD E8 was a 2,250 horsepower passenger train diesel locomotive built by General Motors' Electro-Motive Division (EMD) between August 1949 and January 1954. It succeeded the EMD E7 and was, in turn, superseded by the EMD E9.

The E8 used two 12-cylinder model 567A engines, each producing 1,125 horsepower. These engines powered generators that supplied electricity to the traction motors on each axle. The locomotive was typically configured in an A-unit (with a cab) and a B-unit (booster, without a cab) arrangement, although single A-units were also operated.

The E8 was a popular choice for many railroads across the United States, and served primarily in long-distance passenger service, hauling trains like the Super Chief, City of Los Angeles, and Broadway Limited. These locomotives were known for their smooth ride, reliability, and stylish design, featuring a streamlined carbody and prominent stainless steel trim.

While most E8 locomotives were retired from mainline service by the 1970s with the decline of passenger rail travel, some continued to operate for commuter railroads and in excursion service. Several E8 locomotives have been preserved and can be seen at museums and heritage railways today.
