The EMD SD70 is a series of diesel-electric locomotives produced by the Electro-Motive Division (EMD) of General Motors beginning in 1992. Over 4000 locomotives in this series have been produced, and the type continues to be produced though EMD is no longer owned by General Motors. Introduced in 2004, the SD70ACe was designed to meet the latest EPA emissions regulations and featured a few other modifications over previous models, including AC electric motors for increased reliability and HTSC bolster-less trucks for simpler maintenance. Rated at 4,300 horsepower, the SD70ACe is in use on a number of railroads across the US.
