<P> Services are provided by seven - car S Stock, part of Bombardier's Movia family, with air - conditioning as the sub-surface tunnels (unlike those on the deep - level tube lines) are able to disperse the exhausted hot air . These trains have regenerative brakes, returning around 20 per cent of their energy to the network . With a top speed of 62 mph (100 km / h), a 7 - car S Stock train has a capacity of 865 passengers, compared to 739 for the six - car C Stock train it replaced . With a length of 384 feet (117 m), S Stock trains are 79 feet (24 m) longer than 305 - foot (93 m) long C Stock trains and station platforms have been lengthened . Traction voltage was increased in 2017, from the present nominal 630 V to 750 V to give better performance and allow the trains to return more energy to the network through their regenerative brakes . </P> <P> The line's depot is at Hammersmith, close to Hammersmith station, built by the Great Western Railway to be operated by the Metropolitan Railway when the joint railway was electrified in the early 20th century . Sidings at Barking and near High Street Kensington (Triangle Sidings) stable trains overnight . Sidings at Farringdon were used during the C stock era; due to the greater length of the new S stock trains, these are no longer in use . </P> <P> Together with the introduction of S Stock trains, the track, electrical supply and signalling systems are being upgraded in a programme planned to increase peak - hour capacity on the Circle and Hammersmith & City lines by 65 per cent by the end of 2018 . A single control room for the sub-surface railway opened in Hammersmith on 6 May 2018 and an automatic train control (ATC) system will replace signalling equipment installed from the 1940s . The cross-London Crossrail line, planned to open in 2018, is expected to reduce crowding between Paddington and Whitechapel . </P> <Table> <Tr> <Th> Station </Th> <Th> Image </Th> <Th> Opened </Th> <Th> Additional information </Th> <Th> Position </Th> </Tr> <Tr> <Td> Hammersmith </Td> <Td> </Td> <Td> 13 June 1864 </Td> <Td> Moved to current position 1 December 1868 . </Td> <Td> 51 ° 29 ′ 39" N 000 ° 13 ′ 30" W ﻿ / ﻿ 51.49417 ° N 0.22500 ° W ﻿ / 51.49417; - 0.22500 ﻿ (01 - Hammersmith tube station) </Td> </Tr> <Tr> <Td> Goldhawk Road </Td> <Td> </Td> <Td> 1 April 1914 </Td> <Td> </Td> <Td> 51 ° 30 ′ 07" N 000 ° 13 ′ 37" W ﻿ / ﻿ 51.50194 ° N 0.22694 ° W ﻿ / 51.50194; - 0.22694 ﻿ (02 - Goldhawk Road tube station) </Td> </Tr> <Tr> <Td> Shepherd's Bush Market </Td> <Td> </Td> <Td> 13 June 1864 </Td> <Td> Moved to current position 1 April 1914 .
