Sudbury Town station was opened on 28 June 1903 by the
District Railway (DR, now the
District line) on its new extension to
South Harrow from
Park Royal & Twyford Abbey. This new extension was, together with the existing tracks back to
Acton Town, the first section of the Underground's surface lines to be
electrified and operate
electric instead of
steam trains. The Deep level tube lines open at that time (
City & South London Railway,
Waterloo & City Railway and
Central London Railway) had been electrically powered from the start. The original station building was demolished in 1930 and 1931 and replaced by a new station in preparation for the handover of the branch from the District line to the Piccadilly line. The new station was designed by
Charles Holden in a modern
European style using brick,
reinforced concrete and glass. Like the stations at Sudbury Hill to the north and Alperton to the south as well as others that Holden designed elsewhere for the east and west Piccadilly line extensions such as
Acton Town and
Oakwood, Sudbury Town station features a tall block-like ticket hall rising above a low horizontal structure that contains station facilities and shops. The brick walls of the ticket hall are punctuated with panels of
clerestory windows and the structure is capped with a flat concrete slab roof. Sudbury Town station is a Grade II*
listed building. Some of the original station signage uses the
Johnston Delf Smith typeface, a
wedge-serif variation of the standard London Underground
Johnston typeface. On 4 July 1932, the Piccadilly line was extended to run west of its original terminus at
Hammersmith sharing the route with the District line to Ealing Common. From Ealing Common to South Harrow, the District line was replaced by the Piccadilly line. ==Services==
