The predecessor, a neo-gothic station, was built by the London and Windsor Railway on the west of London Road bridge, opening on 22 August 1848. Preparatory work for rebuilding by the Southern Railway in its "Southern Odeon" style on the east of London Road was halted by the outbreak of World War II, with most trackwork and the vertical edgings of the five planned through platforms in place. After the war some platforms were made level for rugby spectators' trains which were hand-flagged through the station. On 28 March 1954 a completely rebuilt station came into use with three through tracks. The two main up platforms face each other. The slower of these sees more than half of services join from a flyover to the south which coupled with the three tracks to St Margarets ensures no hold-ups needed to fast services eastbound. Platform 1 has not existed as a functioning entity since before 2003; platform 2 has had the conductor rails removed between 2003 and 2006. The trackbeds of both are now obstructed by temporary buildings. Platform 3 has a direct access from the street available via a queuing area used during events at Twickenham Stadium. On 4 February 1996, South West Trains ran the first re-privatised service nationally. This ran from Twickenham to London at 05:10. The last regular-scheduled privatised train on the main network was 48 years before.
Services
The typical off-peak service from the station in trains per hour is:
The station is on bus routes to places including Brentford, Whitton and Hounslow. A taxi rank adjoins the booking hall.
Future
The RFU had petitioned the government to improve the station to be ready to handle the increased use during the 2015 Rugby World Cup. Network Rail invested in plans in partnership with Kier Property and new rolling stock was ordered. The partnership's boldest plans were countered by a residents action group. The Supreme Court refused leave to appeal from a series of pro-plan rulings in Summer 2013. The process led to reduced density and aesthetically enhanced plans and construction started in 2017. Enlargement of the complex to be mounted on a broad "podium", an outside street-level plaza, about 115 apartments, new retail units and a permanently open at-grade northern access point are being built in a programme of works forecast to end in 2020. The works include two northern entrances with direct access and footbridge access respectively to platforms 2 and 3 ; and a riverside walk beside the Crane, a large stream or small river linked to its associated Moor Mead park in Twickenham.
