The EMD F7 is a model of 1,500-horsepower (1,100 kW) diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).
The EMD FP45 is a cowl unit type of C-C diesel locomotive produced in the United States by General Motors Electro-Motive Division (EMD). It was produced beginning in 1967 at the request of the Atchison, Topeka and Santa Fe Railway, which did not want its prestigious Super Chief/El Capitan and other passenger trains pulled by freight style hood unit locomotives, which have external walkways.
The biggest buyer of this model was the Atchison, Topeka and Santa Fe Railway, now Burlington Northern Santa Fe, with 51 units; an additional 25 were delivered in early 1996, during the merger process. The Santa Fe's SD75Ms were the railroad's last new locomotives, with the last new unit, number 250, built in August 1995. [2]

The Santa Fe CF7 is an EMD F-unit railroad locomotive that has had its streamlined carbody removed and replaced with a custom-made, "general purpose" body in order to adapt the unit for switching duty. All of the conversions were performed by the Atchison, Topeka & Santa Fe Railway's Cleburne, Texas, workshops between February 1970 and March 1978.
The first units produced for a customer were built in December 1940 and January 1941 for the Atchison, Topeka and Santa Fe Railway and numbered the 100 set. These were the first diesel-electric locomotives ever produced with dynamic braking, a system developed at the insistence of the railroad and with its assistance. Initially the four-unit ...
The SD26 were EMD SD24 diesel locomotives rebuilt by the Atchison, Topeka and Santa Fe Railway between January 1973 and January 1978. In an effort to spare the cost of purchasing new motive power, the Santa Fe elected to expand on the success of its CF7 and other capital rebuild programs and extend the life of its fleet of 80 aging SD24s by rebuilding them at its San Bernardino, California Shops.
The initial three locomotives were AB pairs built to haul the Santa Fe's Super Chief diesel streamliners, while the others were built as single A units to haul shorter trains. The locomotives were diesel-electrics with two 900 hp (670 kW) Winton 201-A engines each, with each engine driving its own generator to power the traction motors.
