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:
“The stone often recoils on the head of the thrower.”
—Elizabeth I (1533–1603)
“It is in vain that we would circumscribe the power of one half of our race, and that half by far the most important and influential. If they exert it not for good, they will for evil; if they advance not knowledge, they will perpetuate ignorance. Let women stand where they may in the scale of improvement, their position decides that of the race.”
—Frances Wright (1795–1852)
