There are 12 major underground lines, to avoid confusion each of the lines have different names and color coding. The 12 lines are the Bakerloo line, Central line, Circle line, District line, Hammersmith & City line, Jubilee line, Metropolitan line, Northern line, Piccadilly line, Victoria line, Waterloo & City line and the East London line.
The Underground covers over 400 km of track distance and has 270 stations. Over a billion people utilize the Tube and thus reducing a lot of congestion on London roads. Oyster card, a smartcard has been the latest addition to the ticketing system for Tube. It is cheaper to operate than old payment methods like cash ticketing or magnetic-strip-based Travel cards.
