Northfields Depot

Northfields Depot is a London Underground depot in Northfields in the London Borough of Ealing. It is situated between Northfields and Boston Manor stations on the Piccadilly line.

History
Northfields Depot was built for the western extension of the Piccadilly line and opened on 4 July 1932. Construction of the depot required the existing Northfields station to be rebuilt nearer to South Ealing station.

Until 1964, the depot was also used by District line trains which ran to Hounslow West.
