London Buses route 90 is a Transport for London contracted bus route in London, England. Running between Northolt and Feltham, it is operated by Metroline.
Route 90 commenced on 19 April 1989 between Kew Gardens Station and Northolt Station via Richmond - Twickenham - Staines Road - Hanworth - Feltham - Faggs Rd - Hatton Cross - Harlington - Hayes - Church Road - Lansbury Drive - Kingshill Avenue - Yeading White Hart. The route is a renumbering of route 90B. It was initially operated by London Buslines operating from their Southall (BL) garage using Alexander bodied Leyland Olympians.
On 9 November 1991, it was extended to Northolt station at all times and withdrawn between Richmond and Kew, this section being replaced by new route 391.
On 11 June 1994, the route was diverted at Hayes via Coldharbour Lane instead of Church Road in order to serve new Sainsbury's Store at "The Grapes".
On 23 August 1997, the route passed to Metroline operating from their North Wembley (NW) garage and was converted to low floor single deck operation using brand new Plaxton Pointer bodied Dennis Dart SLFs. The route was withdrawn between Richmond and Feltham Station, that section being taken over by new route 490, and was diverted at Feltham to Browells Lane Leisure West at the same time.
In June 1998, Plaxton Pointer 2 bodied Dennis Dart SLFs were introduced.
In February 2003, due to overcrowding the Plaxton Pointer and Plaxton Pointer 2 bodied Dennis Dart SLFs were replaced by dual-doored Plaxton Pointer bodied Dennis Dart SLFs.
On 25 March 2006, the route was rerouted via Eastern Perimeter Road between Hatton Cross and Harlington Corner upon closure of Eastchurch Road.
On 29 April 2006, the allocation was transferred to Perivale East (PV) garage.
On 1 September 2007, the route was retained by Metroline using brand new MCV Evolution bodied MAN 12.240s.
On 26 November 2011, the allocation was transferred to Perivale West (PA) garage and the MCV Evolution bodied MAN 12.240s were replaced by Plaxton Pointer 2 bodied Dennis Dart SLFs.
On 1 September 2012, the route was retained by Metroline with MCV Evolution bodied MAN 12.240s reintroduced.
