The RP14BD is a diesel-electric switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having two 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]
RP14BDs are rebuilt from older locomotives. [2] They can be built with or without an operating cab.[ citation needed ]
