London Buses Route S1 is a Transport for London contracted bus route in London, England. Running between Lavender Fields and Banstead, it is operated by Metrobus.
Route S1 commenced operation on 27 November 1993, running between Beddington Corner and Sutton via Mill Green Road - Middleton Road - Peterborough Road - Revesby Road - Green Wrythe Lane - Middleton Circle - Middleton Road - Robertsbridge Rd - St Helier Hospital - Wrythe Lane - Erskine Road - Oakhill Road - Sutton Green - Sutton - Carshalton Road - Langley Park Road - Cavendish Road - Brighton Road - Sutton Station running as a Mon-Sat service (Except evenings), using mainly previously unserved roads. It was intially operated from London & County from their Croydon (CN) Garage.
At first, the Sutton end had a deviation incorporating Langley Park Road before buses got to Sutton, but this was altered to a loop working on 21 May 1994.
On 21 May 1994, the route was rerouted to operate a one way loop via Carshalton Road - Langley Park - Cavendish Road and Brighton road instead of running both ways via Langley Park.
On 1 January 1995, route S1 was included in the sale from London & County to London Links.
The service via the north of Langley Park Road was replaced by route S3 with route S1 rerouted to Banstead to replace route 80. Between Sutton and Belmont, the route was diverted via the south end of Langley Park road, replacing route S3.
On 11 October 1997, London General suffered a severe staff shortage, and as a result surrendered several of its services, one being the S1. This was when Quality Line took over, but they did not want the now known to be unreliable Marshall Minibuses and opted for Optare MetroRiders instead. This was one of the rare cases where a route was converted from low floor to high floor buses.
On 19 April 1998, the route was improved with an evening and Sunday service introduced. At the same time, the Optare MetroRiders were replaced and converted to a low floor operation using low floor Plaxton Pointer 2 bodied Dennis Dart SLFs.
On 22 January 2000, the route was extended from Beddington Corner to Hackbridge.
On 1 December 2001, the route was retained by Quality Line with the Plaxton Pointer 2 bodied Dennis Dart SLFs replaced by brand new Alexander ALX200 bodied Dennis Dart SLFs. The route was diverted at Beddington Corner to Mitcham instead of Hackbridge at the same time.
On 10 January 2004, the Sunday and Evening service got given increased frequencies.
On 5 November 2005, the route was rerouted back to run via Revesby Road instead of Middleton Road.
On 2 December 2006, the route was retained by Quality Line with brand new East Lancs Esteem bodied Alexander Dennis Enviro 200 Darts introduced alongside the existing Alexander ALX200 bodied Dennis Dart SLFs.
In Feburary 2007, the route was converted to a full East Lancs Esteem bodied Alexander Dennis Enviro 200 Dart operation.
On 30 November 2013, the route was retained by Quality Line with brand new Optare MetroCitys introduced alongside the existing the East Lancs Esteem bodied Alexander Dennis Enviro 200 Darts.
On 12 April 2014, the route was extended from Mitcham to Lavender Fields. At the same time, the route was withdrawn between Mitcham Junction and Fair Green and diverted via Cranmer Road.
On 10 July 2014, the route was converted to a full Optare MetroCity operation. At the same time an existing Optare Metrocity demonstrator was introduced alongside the existing Optare Metrocitys.
On 1 December 2018, the route was retained by Quality Line.
On 3 July 2021, the route passed to Metrobus operating from their Croydon (C) garage using existing Optare MetroCitys, an existing 9.3m Alexander Dennis Enviro 200 Dart and an existing 10.2m Alexander Dennis Enviro 200 Dart (On loan from London United RATP). At the same time, the route was given a new timetable but with no additional changes to stops served or the frequency of how often the buses run and the Optare Metrocity demonstrator was withdrawn.
In October 2021, the existing 10.2m (On loan from London United RATP) was transferred back to London United RATP and replaced by further existing 10.2m Alexander Dennis Enviro 200 Darts (Owned by Metrobus).
This route will re-routed between Wrythe Lane and Middleton Road via Bishopsford Road and Green Wrythe Lane. In Belmont, it would be re-routed via Cotswold Road rather than Belmont Station. It would also use longer buses to increase capacities. From (TBA)
