London Underground travellers have suffered fresh delays and disruption because of a cracked rail, continuing a week of “chaos” on the Tube.
The Jubilee line – used by more than 500,000 passengers a day – was suspended through central London during the morning peak period, with other lines becoming packed as commuters switched to other routes.
The new delays followed a public apology by London Underground managing director Mike Brown for problems caused earlier this week.
Thousands of passengers suffered major disruption after being forced to walk along the tracks through darkened tunnels from stranded trains on two lines on Monday and Tuesday.
“Our customers deserve much better than the service they have had in recent days and all our energies are focused on delivering a fast, reliable and safe service,” Mr Brown said on Tuesday evening.
Bob Crow, general secretary of the Rail Maritime and Transport union said: “The cracked rail this morning following on from the power failures earlier in the week continues a week of chaos on the Tube.
“The Tube is now in meltdown, and this morning’s problem is on a line supposed to have been upgraded at massive cost under the public private partnership.”
Members of the RMT and the Transport Salaried Staffs Association are due to take two days of strike action next month in a row over job cuts, which would cause massive disruption to services.
The unions have already held two strikes and are pressing ahead with plans for the next walkouts unless talks at the conciliation service Acas lead to a breakthrough in the deadlocked dispute.
An LU spokesman said: “The Jubilee line is currently suspended between Finchley Road and Waterloo due to emergency engineering work in the Green Park area.
“A cracked rail was identified during our routine maintenance check and we are working to rectify the problem as quickly as possible. We apologise for the inconvenience caused.”
