The fleet of 1996 stock trains, running on the London Underground's Jubilee line was purchased to support the opening of the newest section of the Jubilee line (known as the Jubilee Line Extension), which runs from Green Park to Stratford. However, delays in the JLE's opening meant that 1996 Stock was introduced, completely replacing the existing fleet of 1983 Stock, between Christmas Eve 1997 and July 1998 - over a year before the JLE was opened. The earlier trains (1983 stock) were originally planned to be refurbished with the same exterior and interior as the 1996 stock but the cost proved prohibitive.
Both the 1996 Stock and the similar 1995 Stock found on the Northern line were built by Alstom in Birmingham, The 1995 and 1996 stock have different seating layouts and cab designs. The trains are capable of automatic train operation as on the Victoria line, although this will not be enabled until a signalling upgrade in some years' time.
