Tube commuters are braced for another morning of rush hour travel chaos after disruption hit several London Undergroundlines.
Signal failures sparked severe delays on the Victoria, Northern and District lines, while the Piccadilly line and Central lines offered a reduced service as repairs were carried out to its fleet of trains.
Last night, Transport for London told the Standard the delays to the Piccadilly line would persist for a fortnight while engineers “work around the clock” to repair damaged trains.
Passengers using the line – the fourth busiest on the London Underground network - have already faced days of severe delays after “wet leaves on the track” damaged the wheels on several trains.
TfL apologised to customers for the delays.
Lighting and motor repairs were also being carried out to Central line trains causing delays until about 8am, TfL said.
A signal failure at Finchley Central at about 5am today meant the Northern line was suspended between that station and Mill Hill East.
A faulty train added to the disruption on the line with minor delays between Camden Town and Edgware.
The Victoria line was suspended between Finsbury Park and Walthamstow Central after a signalling problem at about 6am.
Service later resumed with severe delays and passengers have been advised to avoid Seven Sisters station. Normal service on the line resumed shortly before 8am, TfL said on Twitter.
The District line had minor delays between Earl's Court and Wimbledon after another signal problem at Earl's Court.
The DLR was also suspended between Bow Church and Stratford due to an obstruction on the track.
A TfL spokesperson said: “We apologise for the disruption experienced by our customers to their journeys this morning.
"Several of our lines were disrupted due to signal failures and faulty trains. Our engineers have been working hard to rectify the issues and return to a high level of service as quickly as possible.”
