The RP20CD is a diesel-electric road switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having three engine-generator sets.

The engines are computer controlled, with the computer stopping and starting engines on a rotating basis, as required to produce the horsepower needed at any given moment.[1]

It has six-wheel trucks, rather than the usual four-wheel trucks commonly found on smaller, lighter, switcher locomotives. RP20CDs are rebuilt from older locomotives and can be upgraded to 2,700 horsepower (2.01 MW) by adding a fourth generator. [2]
