Piccadilly Circus tube station is the London Underground station located directly beneath Piccadilly Circus itself, with entrances at every corner. Located in Travelcard Zone 1, the station is on the Piccadilly line between Green Park and Leicester Square and on the Bakerloo line between Charing Cross and Oxford Circus.
Piccadilly Circus is a proposed stop on the Chelsea-Hackney Line, also known as the Crossrail 2. It would be between Victoria and Tottenham Court Road stations. Effectively a new station would have to be built under the existing levels, possibly as part of a major overhaul of the existing buildings. However there will only be a stop at Piccadilly Circus if the Chelsea-Hackney Line is part of the London Underground network and not part of the National Rail network. This is the same situation with many stations on the proposed route in Central London. The Chelsea-Hackney Line is not likely to be completed until at least 2022.
