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.[http://www.rjcorman.com/rp_fuel.html Fuel] {{webarchive|url=https://web.archive.org/web/20110728112339/http://www.rjcorman.com/rp_fuel.html |date=July 28, 2011 }}, R.

RP14BDs are rebuilt from older locomotives.[http://www.rjcorman.com/rp_specs.html Specifications] {{webarchive|url=https://web.archive.org/web/20110314173609/http://www.rjcorman.com/rp_specs.html |date=March 14, 2011 }}.
