With finance guaranteed by the government the Piccadilly lines and Metropolitan were extended in the early 1930s. The Metropolitan opened a line from Wembley Park to Stanmore, and the Piccadilly line was to extend north from Finsbury Park to Cockfosters and west from Hammersmith and took over the District line Harrow and Hounslow branches. Several stations were rebuilt in a Modernist style influenced or designed by Charles Holden, who called them his 'brick boxes with concrete lids'. Piccadilly line trains took over the District service to South Harrow in 1932, reaching Uxbridge the following year. Piccadilly trains reached Cockfosters and Hounslow West in 1933, although District line services to Hounslow continued until 1964.
