Tube delays: Rail passengers facing hold-ups as more problems hit London Underground

Londoners today faced yet another morning of travel chaos after signal failures sparked severe delays on the Tube and rail networks.

Tube commuters experienced disruption on the Hammersmith and City, Metropolitan and Circle lines after signal failures at Moorgate and Barbican stations.

A “fire alert” in the signalling centre at Fenchurch Street station caused delays to train services.

Tube bosses were forced to apologise to passengers for the second day running as services were severely delayed in both directions on all three London Underground lines.

The disruption follows a chaotic rush-hour yesterday morning with huge overcrowding on the Victoria line, including "crush" conditions when Seven Sisters station was shut to relieve platform congestion.

Customers hit out at the delays online.

Arial Bold tweeted: "Don't get the Circle Line this morning. Unless you fancy confronting a gaping chasm of Kafkaesque despair for 30 mins on a freezing platform."

Another Twitter user James Darling wrote: "The Circle Line is a lie."

Anisa Moin said: “Being told one thing by the driver and another by the station announcements... are we leaving or aren't we? Just another day on the @metline.”

Mark Hirst tweeted: "Awful service on the @metline today. Delayed trains, destination changes at the last minute and no-one that knows what's happening."
