Wembley Park tube station

Until 1880 the Metropolitan Railway (MR) line out of London only ran as far as Willesden Green. In early 1879 work began to build an extension to Harrow-on-the-Hill, with one additional station at Kingsbury and Neasden. Services to Harrow started on 2 August 1880, extending the MR route (today's Metropolitan line) into Middlesex.[7] At this time Wembley was a sparsely populated rural area which did not merit the construction of a railway station and MR trains passed through without stopping. In his 1973 BBC documentary Metro-land, Sir John Betjeman remarked, "Beyond Neasden there was an unimportant hamlet where for years the Metropolitan didn't bother to stop. Wembley. Slushy fields and grass farms."[8] However the then chairman of the MR, Edward Watkin, was an ambitious businessman who sought new ways of attracting paying passengers out of London and onto his railway, and he regarded the barren lands of Wembley as a business opportunity.

In 1881 Watkin purchased large tracts of land close to the MR line and began a grand scheme to build an amusement park at Wembley, laid out with boating lakes, a waterfall, ornamental gardens and cricket and football pitches. The centrepiece of this park was to be a soaring metal tower, known as Watkin's Tower; at 1,200 feet (366 m) it was to be taller than the Eiffel Tower and would offer panoramic views of the surrounding countryside, just 12 minutes from Baker Street station.[9] Wembley Park station was specially constructed to serve these pleasure grounds as a destination for excursion trips on the company's trains.[10] The station opened for the first time on 14 October 1893 and initially operated to serve only Saturday football matches in the park. It opened fully on 12 May 1894.[11]

Watkin confidently anticipated that large crowds would flock to the park and the railway station design incorporated additional platforms to handle large passenger numbers.[12] Watkin's Tower ran into structural and financial difficulty; it was never completed and the partially built structure was demolished in 1904. Despite this, Wembley Park itself remained a popular attraction and flourished.

Later in the 1890s, the Great Central Railway's (GCR's) London extension was constructed adjacent to the MR's tracks. The tracks pass under the entrance building but the station has never been served by main line operators. In 1905 the tracks were electrified and the first electric trains became operational. Between 1913 and 1915, the MR added additional tracks to double the line's capacity.[13]

From 1915 the MR began a programme of selling off its surplus land holdings in Buckinghamshire, Hertfordshire and Middlesex for suburban housing development. Its Metropolitan Railway Country Estates Limited marketed areas such as Wembley Park under the "Metro-land" brand, promoting modern homes in beautiful countryside with a fast railway service to central London.[14] The MR sold the park land at Wembley when the site was selected to host the 1924 British Empire Exhibition and the grand British Empire Exhibition Stadium constructed for this event was later to become Wembley Stadium, the home ground of the England national football team.[15]

On 10 December 1932, the MR opened a branch line north from Wembley Park to Stanmore.[11] Originally, the MR served all stations south from Wembley Park to Baker Street station but the line suffered from congestion due to limited capacity on the tracks heading into Baker Street. Following the combination of the MR and London's other underground railways to form the London Passenger Transport Board (LPTB) in 1933, the LPTB took steps to alleviate the congestion by constructing new Bakerloo line tunnels from Baker Street to connect to the Metropolitan's tracks south of Finchley Road station. From 20 November 1939,[16] the Bakerloo line then took over the Metropolitan stopping services between Wembley Park and Finchley Road and the Stanmore branch.

Following World War II, London was chosen to host the 1948 Olympic Games. To handle the exceptional number of spectators visiting Wembley Stadium, the original station building was extended, with a new ticket hall, additional circulation routes and platform stairs. This was built in a red-brick modernist style. At the opening of the Jubilee line on 1 May 1979, the Bakerloo service from Baker Street to Stanmore was transferred to the new line.

When the UEFA European Football Championship was held at Wembley in 1996, a large temporary staircase was constructed leading down from the 1948 extension and under the newly built Bobby Moore Bridge, which had opened in 1993. Intended as a temporary structure, the staircase remained in its unfinished state until 2004 when station upgrade works commenced.[17]

As part of the Wembley Stadium redevelopment in the early 2000s, the station was comprehensively rebuilt and expanded, increasing capacity by 70%. Costing £80m,[18] the work included a significantly larger ticket hall, additional footbridges, widened stairs to Olympic Way and 5 lifts to provide step-free access. To cater for event crowds, event day entrances/exits were also constructed.[19] Undertaken by Tube Lines, the expansion was completed in 2006, prior to the completion of the delayed Stadium project.[20][21] The provision of additional platforms for Chiltern Railways services was considered, but was not proceeded with.[22]

In the early 2020s, Transport for London proposed a new residential development on land adjacent to the station currently used as car parking. This development of over 450 new homes with Barratt Homes was approved by Brent Council in Dec 2020.[23]
