The Piccadilly Line is a line of the London Underground, coloured dark blue on the Tube map.
The line was opened as the Great Northern, Piccadilly & Brompton Railway in 1906, having been formed from the amalagamation of three planned tube railways: the Great Northern and Strand Railway, the Brompton and Piccadilly Circus Railway, and the "Deep-Level District". The original route was from Finsbury Park to Hammersmith[?]. The line was expanded rapidly in the 1930s, taking over two branches of the District Line in the west, and extending through new tubes and surface tracks to Cockfosters[?] in the north-east. These extensions are notable for the modern architecture of their stations, many designed by Charles Holden[?].
From 1907 to 1994, except during the Second World War, a short branch off the Piccadilly Line served Aldwych tube station.
