The London Underground 1983 Stock was a class of electric multiple unit built by Metro-Cammell for use on London Underground's Jubilee line.
The 1983 Stock was the last train to be designed in-house by London Underground; it was the last conventional Tube train in the long line of evolving design since the 1938 Stock. The stock was built by Metro-Cammell to replace the 1972 Mark II Stock operating on the Jubilee line; in turn this was intended to enable those trains to replace the 1938 Stock on the Bakerloo line. The trains were considered to be unpopular by passengers, and were relatively unreliable in service. They were withdrawn after just 14 years in service, and were replaced by the 1996 Stock.
