Diesel–electric transmission is used on railways by diesel–electric locomotives and diesel–electric multiple units, as electric motors are able to supply full torque from 0 RPM. Diesel–electric systems are also used in marine transport , including submarines, and on some other land vehicles.
An electro-diesel locomotive (also referred to as a dual-mode or bi-mode locomotive) is a type of locomotive that can be powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive). For the most part, these locomotives are built to serve regional, niche ...
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.
Diagram of Priestman oil engine from The Steam engine and gas and oil engines (1900) by John Perry Petrol–electric Weitzer railmotor, first 1903, series 1906. The earliest recorded example of the use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman, which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as ...

Electro-Motive Diesel (abbreviated EMD) is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors , EMD has been owned by Progress Rail since 2010.
The FLXDrive Series of locomotives are GE's first battery-electric locomotives, using a similar design to the Evolution Series, with the exception of a diesel prime mover. The FLXDrive series was introduced in late 2019 with one BEL44C4D demonstrator unit, but other FLXDrive variants are planned for the future.
In 1951, the engines received 4-valve cylinder heads, thus creating Mark II "RK" and "V" types which ran at 750-850rpm. Intercooling became an option in 1960, adding a "C" to the engine designation should it be equipped.
