The station has an island platform with passenger access down from the booking hall. Trains terminating at the station may use either a turnback siding west of the platforms to leave the running lines and run eastwards later or a crossover east of the station for more immediate return to central London. In 2018, it was announced that the station would gain step-free access by 2022, as part of a £200 million investment to increase the number of accessible stations on the Tube. Work eventually began in February 2025 to install lifts and improve accessibility, with completion scheduled for summer 2026. North of the Central line tracks there is the singled track of the Acton–Northolt line from Paddington which is now used by freight trains and previously a single daily passenger "
parliamentary service" (operated by
Chiltern Railways) between Paddington and
Gerrards Cross. There are no longer any platforms on this line. ==Services==
