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 could be considered the last train to be designed 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 1983 tube stock was formed in pairs of three-car units. Fifteen trains were delivered for the Jubilee line in 1983 and a further batch arrived from 1987. They had brightly coloured interiors and modern features, including passenger operated doors. The doors, however, were only single. This slowed down boarding and was a significant factor in the decision to withdraw these trains after just 15 years' service.
