Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Head end power (HEP) or electric train supply (ETS) is a rail transport term for 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 (HEP). Originally, trains hauled by a steam locomotive would be provided with a supply of steam from the locomotive's boiler for heating the carriages. When diesel locomotives and electric locomotives replaced steam, the steam heating was then supplied by a steam-heat boiler. This was oil-fired (in diesel locomotives) or heated by an electric element (in electric locomotives). Oil-fired steam-heat boilers were appallingly unreliable. They caused more locomotive failures on any class to which they were fitted than any other system or component of the locomotive, [citation needed] and this was a major incentive to adopt a more reliable method of carriage heating.show more
