General Electric built the E60 locomotive between 1972 and 1983.
The six-axle 6,000 hp locomotives were built for both passenger and freight service in the United States and Mexico, but they are perhaps best known for their use along the Northeast Corridor.
However, Ferrocarriles Nacionales de México (NdeM), which purchased 39 of the locomotives, was the largest customer. However, many of the units intended for this project did not operate.
The Black Mesa and Lake Powell Railroad (BM&LP) in Arizona also used the E60s to haul coal starting in 1973.
