The British Rail Class 487 electric multiple units were built by English Electric in 1940, for use on the Waterloo & City line.  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, a version of all over blue with grey detailing. 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 for a couple of reasons. They did not feature the normal yellow ends because the route they operated was entirely in tunnel where the darkness would render them pointless (the line did not integrate at all with the rest of the network). 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.

1 vehicle has been preserved.
