EMD TR1

The EMD TR1 was a two-unit cow and calf diesel locomotive built by General Motors Electro-Motive Division of La Grange, Illinois, in 1941. Two pairs were built, all for the Illinois Central Railroad, the only purchaser. The units strongly resembled the NW3, with a long frame, Blomberg B road trucks and a large cab joined to a wide hood that tapered toward the front, and they put the machinery of the EMD FT into switcher bodywork, with a V16 EMD 567 diesel engine of 1,350 horsepower in each unit. The cow and calf were semipermanently coupled with a drawbar rather than couplers. The pairs were numbered 9250 and 9251, later 1350 and 1351, worked first at Markham Yard south of Chicago and by the early 1950s at East St. Louis, and were retired in 1966 and traded in to EMD for new GP40 locomotives.
