A preserved train of 1938 Stock at Amersham station The interior of a 1938 Stock train In service 1938–1988 1989–present on Island Line Manufacturer BRC&W Metro-Cammell from Wikipedia.org: The 1938 Tube Stock is a London Underground tube stock design. A total of 1,121 cars were built by Metro-Cammell and Birmingham RC&W. An additional 173 cars were added to the fleet by the end of 1953, comprising 91 new builds (the 1949 Tube Stock), 76 conversions from Pre-1938 Tube Stock or 1935 Tube Stock, and six unconverted cars of 1935 Tube Stock, and the stock was used on the London Underground until 1988. During their long lives they worked on the Bakerloo, Northern, Piccadilly, East London and Central lines. Some examples are still at work on the Isle of Wight as Class 483, making them the oldest passenger rolling stock operating timetabled services on the National Rail network. The trains represented a major technical advance, as all the electrical equipment was located under the floor for the first time. All previous tube stock had large equipment compartments behind the driving cabs in motor cars, which reduced the space available for passengers.
