Circle Line (place)

The Circle Line is not circular, but is the only London Underground line to contain a proper loop which one can travel right around on the same train. (The Central Line's loop doesn't go through at Woodford, the Piccadilly Line's loop at Heathrow Airport is only a loop back, and is shut right now, and the Northern Line's loop is simply the line splitting and dividing.) The Circle Line incorporates, along its north side, some of the oldest tube route in the world. Entirely in Central London and Travelcard Zone 1, the Circle Line is coloured yellow on the official tube map. The Circle Line touches every other London Underground line except the East London Line.

Apologies to iain for superseding his station-list with a map.

The Circle Line is concurrent with the District Line from Tower Hill to Gloucester Road and from High Street Kensington to Edgware Road; with the Hammersmith and City Line from Paddington (slight walk) to Liverpool Street; with the Piccadilly Line from South Kensington to Gloucester Road; and with the Metropolitan Line from Baker Street to Aldgate. Astute reckoners will see that only the curves between High Street Kensington and Gloucester Road, and between Tower Hill and Aldgate, are unique to the Circle Line.
