The AC6000CW is a 6,000-horsepower (4,500 kW) 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.

A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.

The InterCity 125 set a speed record – 148 mph (238 km/h) – for a diesel-powered train in 1987. Capable of 125 mph (201 km/h) in regular service, the train consists of two power cars with either seven or eight carriages between them.
These locomotives operated by Pacific National in Australia show three styles of diesel locomotive body: cab unit (front), hood unit, and flat-nose (rear).
