It was renamed Northolt (for West End) Halt, before gaining station status under its original shorter name.

It was closed in 1948 when the Central line was extended on a new pair of tracks from North Acton, the current Northolt tube station opening on the opposite side of the road bridge on 21 November 1948.

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.

[7] 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 a single daily passenger "parliamentary service" (operated by Chiltern Railways) between Paddington and Gerrards Cross.
