100 Feltham trams (so named because they were manufactured by the Union Construction Company in Feltham) were built in total, 54 for Metropolitan Electric Tramways and 46 for London United Tramways. They started to enter service in 1931. All 100 Felthams passed to the London Passenger Transport Board in 1933, with many surviving right up to the end of trams in London in 1952. Following withdrawal from London services, many Felthams moved to Northern tram systems such as those in Leeds and Sunderland.
