A power failure is causing major disruption across the London Underground network, London Overground and the Elizabeth line.
The Bakerloo, Weaver and Waterloo & City lines are currently suspended, as is part of the Mildmay lines, while there are severe delays on the Jubilee and Piccadilly lines, as well as the Elizabeth line.
Transport for London (TfL) said the issues had been caused by a power outage in south-west London which happened at about 14:30 BST. Power has since been restored, but delays and line suspensions are ongoing.
Separately, the entire Suffragette line on London Overground is suspended due to a fire alert.
Waterloo station is among the worst affected stations, as it is usually served by Jubilee, Northern and Bakerloo line trains.
Earlier, the Northern and Jubilee lines were part suspended, as was the Elizabeth line. The Northern line currently has minor delays.
The Transport for London (TfL) website also appears to be suffering from intermittent issues with some travel advice pages not loading.
A spokesperson for TfL said the outage was a result of a National Grid issue, which had shut down everything for a matter of minutes.
He said: “When the power goes out the trains will have stopped. We’ve cleared some stations. Because there’s no electricity it might not necessarily be safe for them to be open.”
TfL says it is in the process of getting things back up and running.
A Tube driver who had been halted at Regent’s Park station said he had been told it could take another two hours before he could move along.
Among those affected by the transport issues were Justine, 53 and Benny, 20, who had travelled to London from the Warwickshire town of Leamington Spa to renew the latter’s passport.
Speaking outside a closed Embankment station, their frustration at being unable to take a normally simple journey to Marylebone station was clear.
“It’s going to be really annoying, I don’t know how to get home,” Justine said.
“We weren’t even able to renew his passport. It was just one of those days.”
