SD90 - Loco Store

The EMD SD90MAC is a 6,000 hp (4,470 kW)[1] C-C diesel-electric hood unit locomotive produced by General Motors Electro-Motive Division. It is, with the SD80MAC, one of the largest single-engined locomotives produced by that company, surpassed only by the dual-engined DDA40X. Currently the Norfolk Southern is close to finishing up a program to rebuild SD90MACs into SD70ACUs, As of late-2018 only a few SD90MACs are still in service on the NS.
