The Circle Line runs from Hammersmith in west London to Edgware Road and carries on to make a loop around Central London via King’s Cross St Pancras, Liverpool Street, Aldgate, Tower Hill, Mansion House, Victoria and High Street Kensington terminating at Edgware Road and then return via the same route back road to Edgware Road and back onto Hammersmith.

History
1863 saw the opening of the Metropolitan Railway on the 10th January which was the world’s first underground railway service which ran between Paddington and Farringdon Street using steam locomotives and wooden carriages, in the same year a select committee report recommended an inner-circle of railway lines connecting built and under construction London termini. The following year the District Railway was formed to build and operate a line from South Kensington to Tower Hill. The Metropolitan Railway was later extended to the west in 1868 from a new station at Paddington to South Kensington.

Metropolitan Railway LogoThe District Railway had been opened between West Brompton and Blackfriars by May 1870, services were first operated by the Metropolitan Railway. The District Railway was extended to Mansion House in 1871 and to Aldgate on 18th November 1876 although due to conflict between the companies work on the inner-circle wasn’t completed, it took an act of parliament before further work was done. The Metropolitan Railway was extended from Aldgate to a temporary station at Tower Hill and the District Railway finished it’s extension to Whitechapel on 6th October 1884, the temporary station at Tower Hill was later replaced by joint station and the inner-circle was finally complete. Clockwise ‘Outer-Rail’ trains were provided by the Metropolitan Railway and the anti-clockwise ‘Inner-Rail’ trains were provided by the District Railway.

The line was absorbed into the London Passenger Transport Board on 1st July 1933 to along with other Underground Railways, tramways and bus operators in London and Metropolitan Railway EMUs were refurbished at Acton Works to become 5 car Circle Stock trains and were originally painted red and cream although were later changed to all over red to reduce costs and until 1940 these trains included first class accommodation. In 1947 F Stock trains transferred to the Uxbridge Line meaning that the 5 car O and P Stock Trains with remotely operated doors used on the line could be transferred to the Circle Line. The Circle Line wasn’t shown as a line separate from the Metropolitan and District Lines until 1949.

In 1959/60 the Circle Line trains were increased to 6 car trains which were the same length as the trains operating on the Hammersmith & City Line which meant that the trains of the two lines could be integrated and maintenance carried out at Hammersmith depot allowing Neasden Depot to concentrate on the new A Stock and in 1970 the trains on both lines were replaced by C Stock Trains with public address systems. One person train operated was proposed in 1972 but didn’t happen until 1984 due to conflict with Trade Unions and in 1998 the infrastructure of the Circle Line was partly privatised in a public-private partnership managed by Metronet. Metronet went into administration in 2007 and was taken over by Transport for London as part London Underground as Nominee SSL.

On 31st May 2008 one day before the new alcohol ban on Transport for London Services thousands of people took to the Circle Line to have a party where 17 were arrested and several stations closed due to disorderly behaviour.

Circle Line Route pre-2009.

In December 2009 the Circle Line was extended to it’s current route, prior to this the line ran a simple circle via Edgware Road, Kings Cross St Pancras, Aldgate, Tower Hill, Victoria and High Street Kensington. Rather than running a circle trains now run from Hammersmith to Edgware Road and then go around the circle before terminating at Edgware Road, the then return via the same route back round to Edgware Road and back to Hammersmith, the purpose of the extension was to improve reliability as trains now have a terminus and increase the service frequency on the Hammersmith Branch.

Rolling Stock

S Stock
The Circle line currently operates 7 car S Stock trains know as ‘S7 Stock’ trains, the trains are built by Bombardier in Derby as part of their Movia family. S7 Stock trains were ordered to replace the C69/ C77 Stock trains which had been in operation on the Circle Line since 1970. S7 Stock trains are longer than the 6 car C Stock trains and so some station platforms have been lengthened, it is planned to increase the traction voltage from 630v to 750v once the whole Sub-Surface network has S Stock trains for better performance and to get better performance from their regenerative brakes. S7 Stock trains entered passenger service on the Circle line on 2nd September 2013 and fully replaced all C Stock trains on 10th February 2014.

Depots

Hammersmith
Hammersmith Depot is the lines main depot near Hammersmith Station, built by the Great Western Railway for the Metropolitan Railway when the joint railway to Hammersmith was electrified in 1906.

Other Depots and Sidings
Heavy maintenance is carried out at Neasden depot, S7 Stock deliveries are delivered to Neasden depot to be readied before transferring them to Hammersmith. The Circle Line also uses sidings at Barking, Farringdon and near High Street Kensington known as ‘Triangle Sidings’ for stabling trains overnight.
