Pinner is a London Underground station on the Metropolitan line in zone 5. The station was opened in 1885 as part of the Victorian expansion of dormitory suburbs, and was one of the stations included in the Metro-land project in the early 20th century. The site is served by several bus routes including links to the Hatch End railway station which was known as Pinner & Hatch End prior to 1920.
The station was opened on 25 May 1885, following a prior expansion to nearby Harrow-on-the-Hill station in 1880. It remained the terminus of the Metropolitan Railway until 1 September 1887 when the line was further extended to Rickmansworth.
London bus routes 183, H11, H12 and H13 serve the station's location and provide services that terminate at Golders Green, Harrow, Mount Vernon Hospital, Northwood Hills, Ruislip, South Harrow and Stanmore.
Access to the southbound platform is step-free from the ticket hall. In order to reach the northbound platform, it is necessary to use a footbridge, which was constructed in 2002. Before this, a subway between the two platforms existed, but this was closed for safety reasons.
