London Underground 1983 Stock

The London Underground 1983 Stock was a class of electric multiple unit built by Metro-Cammell for the Jubilee line. It was the last train designed in-house by London Underground and the last conventional tube train in the long line of evolving design since the 1938 Stock. Only 15 six-car trains were ordered from Metro-Cammell in 1982, because ridership was declining and later phases of the line were cancelled. The first train was delivered in August 1983 and entered service in May 1984, and a second batch of sixteen and a half sets ordered in August 1986 entered service from November 1987. Some trains went back to Metro-Cammell after delivery because they were 18 millimetres too wide. They were withdrawn after just 14 years in service and replaced by the 1996 Stock.
