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 and other passenger trains pulled by freight style hood unit locomotives, which have external walkways. The railroad preferred a cowl unit.
