The British Rail Class 10 railway locomotive was a variation on the Class 08 diesel-electric shunter in which the English Electric engine was replaced by a Blackstone engine and traction motors were either GEC or BTH. The locomotives were built at the BR Works in Darlington and Doncaster over the period 1953-62.
The engine is a Blackstone 6-cyl., 4-stroke, ER6T. Traction motors are either 2 x BTH [D3152-D3166] motors or 2 x GEC nose suspended motors.
BritishRail assigned Class 53 to the single Brush Traction -built prototype locomotive Falcon.
Returning to British Railways in 1963, Falcon spent six months working out of Sheffield on both passenger and freight diagrams, after which its testing was completed.
In 1970, BritishRail approached Brush Traction with a proposal to buy the (by now practically worthless) locomotive for its scrap value, which was accepted by the builder; the loco underwent a rebuild at BREL Swindon, emerging in corporate Rail Blue with full yellow ends and bearing the new number D1200.
Light rail is the successor term to streetcars, trolleys and trams in many locales, although the term is most consistently applied to modern or modernised tram or trolley operations employing features more usually associated with metro or subway operations, including exclusive rights-of-way, multiple unit train configuration and signal control of operations.
Light rail is generally powered by electricity, usually by means of overhead wires, but sometimes by a live rail, also called third rail (a high voltage bar alongside the track), requiring safety measures and warnings to the public not to touch it.
Light rail systems are generally cheaper to build than heavy rail, since the infrastructure does not need to be as substantial, and tunnels are generally not required as is the case with most metro systems.
