EMD SW1504
From Wikipedia, the free encyclopedia
The EMD SW1504 was a 1,500 hp (1,100 kW) diesel locomotive for switching service built by General Motors' Electro-Motive Division. It was sold only to Mexico's national railroad, Nacionales de México; 60 examples were built between May and August 1973. With the breakup of NdeM, the locomotives have passed to the variety of successor railroad operators in Mexico.
The SW1504 was fundamentally a SW1500 mounted on EMD's Blomberg trucks, instead of the Flexicoil trucks or switcher trucks available on the SW1500. The Blomberg truck, universally used on EMD's larger four-axle units, was larger than the Flexicoil truck and required a 2 ft (610 mm) increase in overall length. These locomotives were in many respects a transitory design between the SW1500 and EMD's later MP15DC.
