Commuters on the London Underground face severe travel delays this morning after a signal system crash.
The morning rush hour has been thrown into chaos after several Tube lines are suspended following a signal failure.
The worst-affected lines are the Circle, Hammersmith & City and Metropolitan lines.
Travel on the entire Circle line has come to a halt after the system failure at Baker Street.
Hammersmith & City line has severe delays on the entire line, while the stretch between Barking and Edgware Road is suspended, the latest TfL status update shows.
There is no Metropolitan line service between Baker Street and Aldgate in both directions after the signal failure, which is also causing severe delays on the rest of the line.
Passengers can use their tickets on London buses, Chiltern Railways and the Overground Lioness line.
The Victoria line is experiencing minor delays on the entire route due to a shortage of trains.
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.
The outage was caused by a fire at an electrical substation in Maida Vale, with routes like the Elizabeth and Jubilee lines suspended.
Meanwhile, trains to London King’s Cross have been disrupted after a fire next to the track between the station and Stevenage.
Great Northern, LNER and Thameslink trains could be cancelled or delayed by up to 30 minutes. The disruption is expected to clean by 9am, National Rail said.
