EMD GP38AC

The EMD GP38AC is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between February 1970 and December 1971. It was basically a GP38 with an AR10 alternator instead of the GP38's normal generator.
261 examples of this model were built; railroads that purchased this model include CP, DT&I, GTW, GM&O, IC, LV, L&N, N&W, SLSF, SOU and Pacific Power and Light.
Many were upgraded to full GP38-2 status with the Dash 2 modular electrical cabinet.

Preservation

In June 2020, BNSF 2127, originally Frisco 650 built in February 1971, was donated to the Galveston Railroad Museum, in Galveston, Texas.
