The British Rail Class 482 electrical multiple units were built by Adtranz in 1992, for use on the Waterloo & City Line. The units are almost identical to the 1992 tube stock built for the Central Line.
Ten 2-car units were built, numbered 482501-510. Each unit consisted of a driving motor, numbered 65501-510, and a non-driving motor, numbered 67501-510. Trains were operated using two units semi-permanently coupled, with the driving motors outermost.
The units were built as direct replacements for the elderly Class 487 units, dating from 1940. They were in delivered to traffic in 1992/93, and were painted in Network SouthEast livery. On 1 April 1994, operational control of the Waterloo & City Line transferred to London Underground. Unit numbers and NSE logos were removed shortly after the transfer on some but not all trains, but otherwise the trains remained in as-built condition until refurbishment in 2006.
During 2005, TfL announced plans to shut down the Waterloo & City line for 5 months to refurbish the tunnels, depot and stations. This work included refurbishment of the trains, which were repainted in London Underground livery, and took place between April and September 2006.
