On the Uxbridge branch of the Piccadilly line, it is between North Ealing and Acton Town stations.

[7] This new extension was, together with the existing tracks between Ealing Common and Acton Town, the first section of the Underground's surface lines to be electrified and operate electric instead of steam trains.

The new building, by Charles Holden in a style reminiscent of his designs for the 1926 Morden extension of the City and South London Railway (now part of the Northern line),[9] was constructed in Portland stone and features a tall heptagonal ticket hall with glazed screens to all sides.

The new building opened on 1 March 1931 and is very similar to the reconstructed station at Hounslow West built at the same time, also by Heaps and Holden.

However, at times of disruption it is possible for trains to arrive on platform one and, empty of passengers, then it would have to shunt forward in order to reverse and enter the depot.

The train would then stable, or reverse into platform two in order to re-enter service and continue eastbound.
