EMC 1800 hp B-B

what is it?

Electro-Motive Corporation (later Electro-Motive Division, General Motors) produced five 1800 hp B-B experimental passenger train-hauling diesel locomotives in 1935; two company-owned demonstrators, #511 and #512, the Baltimore and Ohio Railroad's #50, and two units for the Atchison, Topeka and Santa Fe Railway, Diesel Locomotive #1. The twin engine power unit layout and multiple unit control systems developed with the B-B locomotives were soon adopted for other locomotives such as the Burlington Route's Zephyr locomotives built by the Budd Company in 1936 and EMC's own EMD E-units introduced in 1937. The B-B locomotives worked as proof-of-concept demonstrators for diesel power with the service loads of full size trains, breaking out of its niche powering the smaller custom Streamliners.
