The Metropolitan Railway constructed the line between Harrow on the Hill and Uxbridge and commenced services on 4 July 1904 with, initially, Ruislip being the only intermediate stop. At first, services were operated bysteam trains, but track electrification was completed in the subsequent months and electric trains began operating on 1 January 1905. Progressive development in the northMiddlesex area over the next two decades led to the gradual opening of additional stations along the Uxbridge branch to encourage the growth of new residential areas. Rayners Lane opened as Rayners Lane Halt on 26 May 1906, and was named after a local farmer called Daniel Rayner. On 1 March 1910, an extension of the District line was opened from South Harrow to connect with the Metropolitan Railway at Rayners Lane junction east of the station enabling District line trains to serve stations between Rayners Lane and Uxbridge from that date. On 23 October 1933, District line services were replaced by Piccadilly line trains.
Design
The station, more a halt, was rebuilt, following the start of house building in the locality in the 1930s that saw passenger figures rise from 22,000 per annum in 1930 to 4 millions in 1937 by a new station to a design by Charles Holden and Reginald Uren that opened on 8 August 1938.. Work had started in earnest with the opening of a temporary timber booking hall and shops on 14 March 1935 allowing work on the new station to proceed. The station, now Grade 2 Listed by Historic England, features the large cube-shaped brick and glass ticket hall capped with a flatreinforced concrete roof and geometrical forms typical of the new stations built in this period. To the west of the station, there is a reversing siding between the running tracks and, during the day, half of the Piccadilly line service reverses here. Two sidings were located south of the station but these were no longer used: with no connection with the running lines. In late 2017 these sidings were lifted.
