The 1938 Tube Stock is the 'classic' tube stock design, built by Metro-Cammell and Birmingham RC&W, used on the London Underground until 1988.
The only examples still in daily use are the six units that survive operating the 'mainline' service on the Isle of Wight, and allocated TOPS Class 483
In addition, some other units survive in preservation, including cars from the first-built unit, which are preserved at the London's Transport Museum Depot in Acton.
