[citation needed] In January 1995, London United purchased Westlink[3] with garages in Hounslow Heath and Kingston upon Thames.

In November 2009 Transdev purchased NCP Challenger with seven Transport for London contracted routes, 87 buses and garages at Park Royal and Twickenham.

[7][8][9][10] This agreement took effect in March 2011, and RATP Group renamed its newly acquired business London United.

When new, the 11-acre (4.5 ha) site was described as one of the finest plants in the country and was the main depot of London United Tramways with 20 covered tracks.

The garage has never reached its capacity, even taking in much of the work from Twickenham when it closed in 1970, and in 2001 107 buses were allocated.

[citation needed] A London Transport survey in 1947 found that 92 vehicles were allocated to Hounslow, a garage with a capacity of 72.

This was mainly achieved by parking buses on a plot of land behind the garage that was also used to stand vehicles terminating there on layover.

[citation needed] Hounslow's first one-man operated double deckers were MCW Metrobuses delivered in 1982 for routes 111 and 202.

It was also the first garage in London to operate a low-floor bus with the arrival of Wright Pathfinder bodied Dennis Lance SLF in December 1993.

[17] There were plans to relocate the garage away from the town centre, and allow the expansion of the adjoining bus station.

Originally built as Chiswick Tram depot, it had latterly been used to operate the British European Airways bus service between Heathrow Airport and the West London Air Terminal on Cromwell Road.

[citation needed] In 1981 Stamford Brook took on Airbus routes A1 and A2 following the withdrawal of the existing British Airways services between Heathrow Airport and central London.

A recruitment centre was opened on Tolworth Broadway long before building work ever started.
