In rail transport, head end power (HEP) or electric train supply (ETS) is the electrical power distribution system on a passenger train. The power source, usually a locomotive at the front or 'head' of a train or a generator car, generates all the electricity used for lighting, electrical and other 'hotel' needs. The maritime equivalent is Hotel Electric Power.

Famous quotes containing the words head and/or power:
“We may not pay Satan reverence, for that would be indiscreet, but we can at least respect his talents. A person who has for untold centuries maintained the imposing position of spiritual head of four-fifths of the human race, and political head of the whole of it, must be granted the possession of executive abilities of the loftiest order.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Falling in love with a United States Senator is a splendid ordeal. One is nestled snugly into the bosom of power but also placed squarely in the hazardous path of exposure.”
—Barbara Howar (b. 1934)
