when does the hammersmith and city line open
Hammersmith & City line 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.[42][43][44] 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.[43][45] The cross-London Crossrail line, planned to open in 2018, is expected to reduce crowding between Paddington and Whitechapel.[46][47]
