London United Tramways Company Limited was an operator of trams and trolleybuses in the western and southern suburbs of London, UK, from 1894 to 1933, when it passed to the London Passenger Transport Board.
The company was formed in 1894 by the Imperial Tramways Company under the leadership of George White and Clifton Robinson to take over the assets of the West Metropolitan Tramways Company, which had gone into receivership and had operated a horse-drawn tram service from Shepherd's Bush to Acton and Chiswick, and from Hammersmith to the north side of Kew Bridge via Chiswick. A short route ran from the south side of Kew Bridge to Richmond.
LUT relaid the existing track, which was in a poor state of repair, and extended and electrified the system. Electric trams first ran on three routes on 4 April 1901 between Hammersmith and Kew Bridge, between Shepherd's Bush and Kew Bridge (via Chiswick), and between Shepherd's Bush and Acton, London's first electric tram service.
Trams never ran across Kew Bridge – the second (stone) bridge, built in the 1780s, was far too narrow, and very steep on the approach from Brentford – which meant that there was an isolated length of single track of 1.53 miles, with passing loops, from the south side of the bridge, across Kew Green, then south along the Kew Road to the Orange Tree public house 51°27′51″N 0°18′06″W / 51.464228°N 0.301534°W in Richmond.
