The London Tube's Circle Line appears on the London Tube Map as a yellow line and loops around London north of the Thames. It was originally created in 1853 when the Metropolitan Railway opened a line between Paddington and Farringdon Street.
Work on the line stalled for various reasons before its completion in 1884. Despite originally being operated using steam trains, electrification was introduced and took over completely in 1905.

The line took over from many parts of the Metropolitan line, and the success of the circular route led to the construction of further such routes within London:
Despite the success of the original circle, these extra routes did not perform as well and all three were eventually ended, though other services still continue on those lines today.
