Commuters on the London Underground face severe travel delays this morning after a signal system crash.
A signal failure is wreaked havoc on the Tube this morning, causing severe delays while some lines were briefly suspended.
The worst-affected lines were the Circle, Hammersmith & City and Metropolitan lines.
The signal failure at Baker Street was resolved shortly before 10.30am after hours of disruption on some lines.
Travel on the entire Circle line came to a halt after the signal system failure at Baker Street.
Hammersmith & City line had severe delays on the entire line until the issue was resolved.
Earlier, there was no Metropolitan line service between Baker Street and Aldgate in both directions after the signal failure.
Passengers were able to use their tickets on London buses, Chiltern Railways and the Overground Lioness line.
We approached TfL for a comment.
Elizabeth line will have a reduced service between Heathrow Terminals and Paddington station today and tomorrow after 10pm for planned works. Four trains per hour will serve Heathrow Terminals 2 and 3.
Today’s disruption comes a week after several Tube lines ground to a halt following a massive power outage.
