Severe rush hour delays on Tube lines after signal system failure

Commuters on the London Underground face severe travel delays this morning after a signal system crash.

A signal failure is wreaking havoc on the Tube this morning, causing severe delays while some lines were briefly suspended.

The worst-affected lines are the Circle, Hammersmith & City and Metropolitan lines.

Travel on the entire Circle line came to a halt after the system failure at Baker Street.

While service has since resumed, the entire line still has severe delays.

Hammersmith & City line has severe delays on the entire line, the latest TfL status update shows.

Earlier, there was no Metropolitan line service between Baker Street and Aldgate in both directions after the signal failure.

This has been upgraded to minor delays.

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.

The Waterloo & City line also has minor delays after a signal failure in the Waterloo area.

We approached TfL and Network Rail 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.

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.
