The British Rail Class 483 electric multiple units were originally built as 1938 tube stock units for London Underground. They were extensively refurbished between 1989 and 1992 by Eastleigh Works, for use on services on the Isle of Wight's Island Line. This was despite having already been used for nearly 50 years on the London Underground network. The units replaced the even older and life-expired British Rail Classes 485 and 486 units which were introduced in 1967, but were originally built as 'Standard' stock units for the London Electric Railway in 1923. The trains were 83 years old when they were withdrawn in January 2021; they were the oldest passenger trains in Great Britain remaining in regular passenger service at the time. They were withdrawn on 3 January 2021, with the line closed from 4 January until 1 November 2021 for upgrade works, after which they were replaced by Class 484s. Of the six units present on the Island at the time of their withdrawal, all have been confirmed for preservation. |
