London Buses route 3 is a Transport for London contracted bus route in London, England. Running between Crystal Palace and Whitehall, it is operated by Abellio London. History Route 3 started operations on 1 November 1908 between Brixton station and South Croydon. On 19 November 1908, the route was altered at both ends to run between Oxford Circus and South Croydon. From April 1909 it was extended on Sundays to Purley, then to Whyteleafe in August 1909. A month later, route 3 was extended northwards to Camden Town, and was withdrawn between Streatham Common and Whyteleafe. On 3 March 1910, route 3 was withdrawn between Brixton (Lambeth Town Hall) and Streatham Common and re-routed via Effra Road to Brixton. In the same month the route was extended to Hampstead Heath. From 16 June 1912, route 3 became a Monday to Saturday route only, being replaced by the recently introduced 59 on Sundays. On 11 May 1913, a new daily route 3A was introduced between Camden Town and Crystal Palace via route 3 to Brixton, then via Water Lane, Herne Hill, Croxted Road and South Croxted Road. Routes 3 and 3A only ran as such until 17 July 1913, when both routes became daily and exchanged numbers. At the outbreak of World War I in August 1914, the 3A was withdrawn as an economy measure, but was re-instated in October. Route 3 was extended from Crystal Palace to Upper Norwood a month later. By the end of hostilities route 3A had been withdrawn and route 3 ran between Camden Town to Crystal Palace. On 1 December 1924, a new system of route numbering on London buses came into force under The London Traffic Act of 1924. As a result, the short workings of route 3 from Camden Town to Brixton were renumbered 3A. This situation continued until 3 October 1934 when all 3A journeys were renumbered 3. Just before the outbreak World War II, route 3 was replaced on Sundays by a new 3A route, running from Crystal Palace to Oxford Circus and on to Baker Street, Swiss Cottage, Hendon, Mill Hill and Edgware station. This was withdrawn after 15 October 1939 as a wartime economy measure. Route 3 returned to a 7-day operation and remained virtually unchanged for the next 40 years. On 2 January 1993, it was converted to one man operation with the AEC Routemasters being replaced by
