Twelve motor carriages (DMBSO), numbered 51–62, and sixteen trailers (TSO), numbered 71–86, were built. Trains were in various formations, from a single motor carriage, to pairs of motor cars with up to three intermediate trailers.
They were originally classified Class 453 under TOPS but were later reclassified Class 487.
The Waterloo & City line was operated as part of the BR Southern Region. Stock was painted in British Railways green livery, which was replaced by BR Blue in the 1970s. In 1986, the line came under the ownership of Network SouthEast, and their blue, red and white livery was applied.
The Class 487 units were unique on the British Rail network in not requiring yellow ends because the route they operated was entirely in tunnel where the darkness would render yellow ends pointless. Further the line did not integrate at all with the rest of the network. Additionally, the units were only fitted with red lights at the ends, thus the front of the train displayed two red lights instead of the more usual white.
By the 1990s the units were urgently in need of replacing. This came in the form of new Class 482 two-car units, which were delivered to traffic in 1992/93. The final Class 487 vehicles were taken by road to Glasgow for scrap, which was their single longest journey above ground. One vehicle, DMBSO no. 61, was initially stored at the National Railway Museum in York, before being subsequently transferred to the London Transport Museum's Acton Depot.
