Metrobus is a bus operator with routes in south London, and parts of Surrey, Kent & Sussex. Formed through a management buyout in 1983, Metrobus was purchased by the Go-Ahead Group in September 1999. Metrobus previously operated many routes under contract to Transport for London in south and south-east London, but following a restructure, on 1 April 2014 these were transferred to Go-Ahead London.
Crawley garage operated London bus route 465.
In October 2009, there was further expansion in the fleet as Arriva decided to sell their Horsham bus operations to Metrobus. Metrobus took over the operations of route 465. Six Alexander Dennis Enviro 200 Darts used on the 465 continued on that route.
The Beddington Lane depot was opened by Metrobus in December 2005 to house route 127 which had been surrendered early by Centra. Work was completed on the garage buildings in February 2006. This garage took over the London routes that ran from Godstone with the exception of the 146 and 246 which moved to Orpington.
The Green Street Green garage operated London bus routes 119 (night service only on this 24-hour route), 126, 138, 146, 161, 162, 181, 233, 284, 320, 336, 352, 353, 358, 464, B14, R1, R2, R3, R4, R6, R8, R9, R11, and school route 654.
A former farm, Green Street Green depot was for many years the only garage for all of Metrobus' London tendered routes since the award of route 61 in 1986. More recently routes have been operated from Godstone and in December 2005 a new depot was constructed in Croydon to cope with new tender awards. During mid-2005 major reconstruction started on the Green Street Green site to make improvements and provide an expansion. During these works, a temporary base was being used at Polhill in next to the base of what was Southlands Travel.
On 23 February 2013, Metrobus commenced operating route 233.
On 23 March 2013, Metrobus commenced operating route 126.
