The first generation of trams in London started in March 1861 when a horse tramway began operating between Marble Arch and Notting Hill Gate.
Initially, there was strong opposition as, although it was popular with its passengers, the first designs had rails that stood proud of the road surface and created an obstruction for other traffic.
[3] Eventually Parliament passed legislation permitting tram services, on the condition that the rails were recessed into the carriageway and that the tramways were shared with other road users.
[6] Although several towns and cities adopted steam trams, the problems associated with track weight, acceleration, noise and power held back their general acceptance in London.
Meanwhile, Imperial Tramways, under the directorship of James Clifton Robinson, had acquired the worn-out tram network in West London, which it renovated and extended from Shepherds Bush to Acton, Ealing, Chiswick and Uxbridge, as the London United Tramways Company, using overhead electrification throughout[6] and its own network of ornate power stations, starting with Chiswick.
The London County Council Tramways first electric line opened in May 1903 between Westminster Bridge and Tooting and the LCC sold 3.3 million tickets in its third year of business, five times the traffic carried by its horse trams.
Route coverage might have been wider still but the terms of the 1870 Act meant that the passage of new tramways had to be negotiated individually with local authorities, who would sometimes impose prohibitively expensive improvement works as a condition of approval.
LUT accompanied this change by introducing electric trolleybuses using twin overhead wires as a cheaper alternative for 17 miles (27 kilometres) of its routes in 1931.
A Royal Commission on Transport, held between 1928 and 1931, ensured that the tram companies retained complete responsibility for the maintenance of its rails and highway, which was shared with other road users who contributed its wear.
After World War II, shortages of steel and electrical machinery were cited as reasons for not investing in maintenance, while the LCC reported that the service ran at a loss.
[21] Alexander Valentine, one of the five full-time members of the London Transport Executive, saw trams as a major cause of road congestion, which would be relieved by the introduction of buses, with the aesthetic benefit of doing away with overhead wires and their noisy operation.
[22] "Operation Tramaway", the replacement of the tram service by diesel buses, was announced in July 1950 by Lord Latham of the London Transport Executive.
Retirement started in October 1950 and London's final first-generation trams ran in the early hours of 6 July 1952 to a rousing reception at New Cross Depot.
A working London tram can also be seen and ridden on at the East Anglia Transport Museum in Carlton Colville near Lowestoft, Suffolk.
However, in spring 1950, the Highways Committee was presented by the Mayor with the concept of running trams between East Croydon station and the new estate being constructed at New Addington.
Chris Green, upon becoming managing director, Network South East, published his plans in 1987 expanding the concept to take in the Tattenham Corner and Caterham branches and provide a service from Croydon to Lewisham via Addiscombe and Hayes.
Tramlink operates with modern articulated tramcars of Bombardier low-floor design called CR4000, based upon the K4000 type of the Cologne Stadtbahn, with the tram units numbered from 2530.
