British Thomson-Houston (BTH) was a British Engineering company, founded in 1894 to manufacture in the UK, under licence, products patented by an American company (which was to become General Electric). ...

History

Ordered under the Modernisation Scheme as Type 1 locomotives for local passenger and freight traffic in the London area. Fitted with an off-centre cab. This class was troubled by poor reliability and was scrapped relatively early (all withdrawn by March 1971). Almost alarmingly, for their several problems, these locos were arguably the second most successful Type 1s after the British Rail Class 20s - the other two fleets, British Rail Class 16 and British Rail Class 17, were worse. The class 20 locomotives usually work in pairs. ... The CLASS 16 locomotive was ordered under the Modernisation Scheme as a Type 1 locomotive for the Eastern Region; based on prototype No. ... Jump to: navigation, search Ordered as a successor to the pilot scheme Type 1 locomotives, fitted with a centre cab. ...


Technical

The engine was a Paxman 16YHXL with 7 in (178 mm) cylinder bore and 7 ¾ in (197 mm) cylinder stroke. The traction motors were4 x BTH 137BZ, nose suspended with single reduction gear drive. The Main Generator was a BTH RTB10858 and the Auxilary Generator was a BTH RTB7420.


Preservation

Only one Class 15 survives in preservation, having finished its life on carridge heating duties with three classmates. After a few years in store, it was purchased and is now being restored. D8233 represents both Class 15 and Class 16 in preservation, no members of the cosmetically similar Class 16 having survived.
