Later models have a small turbine-powered electrical generator using air pressure from the brake line to power the ETD's radio and sensors. The one-way communication of brake data from the ETD to the locomotive evolved into two-way communication that enables the engineer to apply the brakes from both ends of the train simultaneously in an ...

In engines without overlapping power strokes (such as engines with ...
With most trunk line freight and long-distance passenger trains operated using high power electric locomotives, typically in excess of 7,200 kilowatts (9,700 hp) of power output. Heavy freight is hauled with extremely high power multi-section locomotives, reaching up to 28,800 kilowatts (38,600 hp) on the "Shen 24" series of six section ...
Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive (or a generator car) at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs.
