An EMD GP50 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). It is powered by a 16-cylinder EMD 645F3B diesel engine, which can produce between 3,500 and 3,600 hp (2,610 and 2,685 kW). 278 examples of this locomotive were built by EMD between 1980 and 1985. BN 3110-3162 were all delivered with five cab seats, the final five of these having the cab lengthened 23 in (584 mm) vs. the standard EMD cab. The GP50 retains the same overall length of 59 feet 2 inches (18.03 meters) as the EMD GP38, EMD GP38-2, EMD GP39, EMD GP39-2, EMD GP40 and EMD GP40-2.

In 2014–2015 the Norfolk Southern Railway rebuilt 25 GP50s into the low-emission GP33ECO.
