British Rail Class 483

The British Rail Class 483 electric multiple units were originally built by Metro-Cammell as 1938 tube stock for London Underground, then extensively refurbished between 1989 and 1992 by Eastleigh Works for services on the Isle of Wight's Island Line, replacing the even older Class 485 and 486 units. Eight two-car units were first refurbished, numbered 483001 to 008, and a ninth, 009, followed in 1992. Significant electrical work was needed to renew the wiring and let the trains work from the line's third rail supply, and they were painted in the new Network SouthEast livery. They were withdrawn on 3 January 2021 at 83 years old, the oldest passenger trains in regular service in Great Britain at the time, and were replaced by Class 484 units.
