Night Tube
Underground services might run an hour later on Fridays and Saturdays, but would start an hour later the next morning under this proposal.
Underground services generally never run between 0030 and 0530 to allow time for essential maintenance work to take place. London's Underground network is the oldest in the world and needs a significant amount of maintenance just to keep it in its existing state. It also does not benefit from quadruple tracks (except in a couple of places) like some cities (e.g. New York), where at night one pair can be closed for maintenance whilst trains carry on running on the other pair.
However, to cater for later travellers on Friday and Saturday nights, the Mayor will consult on a plan to extend evening services by an hour - to about 0130 - in place of early morning services, which would then start an hour later, at 0630 on Saturdays and 0800 on Sundays.
According to preliminary research by TfL, about 140,000 passengers would use later Tube services whereas about 55,000 use early morning weekend services, half of whom use them to get to work.
The Mayor will consult on plans to extend Friday and Saturday night tube services by an hour to about 0130, by delaying the start of service the next morning by an hour.
