The GE AC6000CW is an AC-traction, 6,000-horsepower (4,500 kW), six-axle diesel electric locomotive built between 1995 and 2001 by GE Transportation. It is among the world's most powerful single-engined diesel locomotives. The locomotive was designed for extremely high horsepower needs, such as pulling heavy coal and ore trains. Most examples were purchased by two railroads: Union Pacific and CSX. The only other operator of this locomotive was BHP Billiton Iron Ore.
