The SD50F is a type of diesel-electric locomotive built by General Electric (GE) Transportation. It is part of the GE Evolution Series, which includes the AC6000CW, AC6000H, and AC6000HXC locomotives. The SD50F is designed for heavy freight service and is known for its reliability and efficiency.

The SD50F features a 16-cylinder, 2,500 horsepower (1,865 kW) GE 7FDL prime mover, which provides excellent fuel efficiency and low emissions. The locomotive is equipped with a GE 750C traction motor and a GE 750D traction controller, which deliver smooth and responsive acceleration. The SD50F also features a GE 750E auxiliary power unit, which provides power for the locomotive's electrical systems.

The SD50F is available in both 64-foot (19.5 m) and 72-foot (21.9 m) lengths, and can be configured with either two or three traction motors. The locomotive is designed to operate at speeds up to 85 miles per hour (137 km/h) and can pull up to 7,200 tons (6,500 metric tonnes) of freight.

The SD50F has been widely adopted by railroads in North America and has become a popular choice for heavy freight service due to its reliability, efficiency, and versatility. The locomotive is also available in a variety of configurations, including a high-cab version for improved visibility and a low-cab version for improved aerodynamics.
