Once the largest tramway network in the British Isles, London's tramways had belonged to a range of operators until the London Passenger Transport Board was created in July 1933, and this resulted in a great variety of tramcars being operated in the Metropolis. This is one of four volumes to cover the history of electric tramcar operation in the city. The south-west witnessed the London United Tramway's early trolleybus routes as well as the operations of Croydon Corporation, and although many of the routes were to be converted before the outbreak of World War II, a number survived until the conversion of the system in 1950-52.Locations featured include: - Battersea Bridge- Brixton Road- Clapham Junction- Clapham South- Coldharbour Lane- Crystal Palace- Hampton Court- Herne Hill- Hounslow- Kennington- Kingston Bridge- Lavender Hill- Longley Road- Milkwood Road- Mitcham- Purley- Putney Bridge- South Croydon- Streatham- Surbiton- Thornton Heath- Vauxhall- Vauxhall Bridge- Victoria- Victoria Embankment- Wandsworth- Waterloo- West Norwood- Westminster- Wimbledon
