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:
“Each part may call the furthest, brother:
For head with foot hath private amitie,
And both with moons and tides.”

Not seeing, yet still having power of sight—
Gives vain alarums to the inward sense”
