LOCOMOTIVE

This article is about locomotives that run on rails.For the type of heavy-haulage traction engine, seeRoad locomotive (disambiguation). For the Russianfootball club, see FC Lokomotiv Moscow. For the

1960s British band, see Locomotive (band).

Three body styles of diesel locomotive: cab unit,hood unit and box cab. These locomotives areoperated by Pacific National in Australia.

A Green Cargo RC 4 class electric locomotive repainted in its original liveryfor the Swedish 150-year railway anniversary in 2006.

A locomotive is a railway vehicle that provides the motive power for a train.The word originates from the Latin loco"from a place", ablative of locus,"place" + Medieval Latin motivus, "causing motion", and is a shortenedform of the term locomotive engine,[1] first used in the early 19th centuryto distinguish between mobile and stationary steam engines.

A locomotive has no payload capacity of its own, and its sole purpose is to

move the train along the tracks. In contrast, some trains have self-propelledpayload-carrying vehicles. These are not normally considered locomotives,and may be referred to as multiple units, motor coaches or railcars. The useof these self-propelled vehicles is increasingly common for passenger trains,but rare for freight (see CargoSprinter). Vehicles which provide motivepower to haul an unpowered train, but are not generally consideredlocomotives because they have payload space or are rarely detached fromtheir trains, are known as power cars.

Traditionally, locomotives pull trains from the front.Increasingly common outside North America is push-

pull operation, where one locomotive pulls the trainfrom the front and another locomotive pushes it frombehind. In this arrangement the locomotive at therear of the train is controlled from a control cab at thefront of the train. Push-pull operation is generally

infeasible in North America as, even if mid-train ortail-end "helpers" are provided, the front-end mighthave over 26,000 horsepower, net for traction,whereas the mid-train and/or tail-end "helpers" mighthave only 9,000 horsepower, net for traction.

Electrification

Electrification is the process of powering by electricity and isusually associated with changing over from another powersource. The broad meaning of the term, such as in the historyof technology and economic history, usually applies to a

region or national economy. Broadly speaking, electrificationwas the build out of the electrical generating and distributionsystems which occurred in the United States, Britain and othercountries from the mid 1880's until around 1940 and is inprogress in rural areas in some developing countries. This

included the change over from line shaft and belt drive usingsteam engines and water power to electric motors

The electrification of particular sectors of the economyis called by terms such as factory electrification,household electrification, rural electrification or railwayelectrification. It may also apply to changing industrialprocesses such as smelting, melting, separating orrefining from coal or coke heating or chemical processesto some type of electric process such as electric arcfurnace, electric induction or resistance heating orelectrolysis or electrolytic separating.

Electrification was called "the greatest engineeringachievement of the 20th Century" by the NationalAcademy of Engineering

TRACK The track on a railway or railroad, also known as the

permanent way, is the structure consisting of therails, fasteners, sleepers and ballast (or slab track),

plus the underlying subgrade. For clarity it is often

referred to as railway track (British English and UIC

terminology) or railroad track (predominantly in the

United States).

The term permanent way also refers to the track in

addition to lineside structures such as fences etc
