The Circle line is a London Underground service with a “circle-esk” shape, running from Hammersmith to Edgware Road and then looping around central London back to Edgware Road. In December 2009 the Circle loop around the centre of London on the north side of the River Thames was broken at Edgware Road and extended a spur west to Hammersmith – The circle line has become a deflated balloon shape (with string).
Coloured yellow on the tube map, the line has 36 stations, including most of London’s main line railway stations. Most of the route and all of the stations are shared with the District, Hammersmith & City and Metropolitan lines.
The first section opened in 1863 when the Metropolitan Railway opened the world’s first underground line between Paddington and Farringdon with wooden carriages and steam locomotives.
- Aldgate Station is built on a massive plague pit, where more than 1,000 bodies are buried
- You can now no longer go around the Circle Line in a full circle. The Circle Line terminates at Edgware Road – this has ruined the circle line pub crawl!
