The travel chaos commuters are facing due to a Tube strike across the capital is being compounded by delays at London Bridge station.

A signalling problem at the station is causing delays of up to an hour to Southern and Thameslink services to and from the station, which are likely to last until at least 10:30pm, according to the Thameslink Railway website.

A spokeswoman from Network Rail told The Independent that trains will continue to run as staff members manual talk trains past a signal.

“Engineers are on site and are fixing the problem as quickly as possible but delays are expected to continue until at least 2100. We apologise to anyone affected by this,” she said.

The signal problems were reported at 6:10pm, just minutes after the Tube strike started.

Southern Rail has tweeted that rail tickets will be accepted on London buses, which are already under strain due to the city-wide Tube strike.

Commuters waiting at the station are tweeting their frustrations, with one describing London Bridge as a "tin of sardines".

Meanwhile, Londoners are attempting to navigate the capital without using the London Underground system, which closed for a 24-hour strike at 6:00pm.

Transport for London has urged commuters to start their journeys early on Thursday as alternative modes of transports will be extremely busy. The organisation has also warned that the delays are likely to pass into Friday morning.

Workers from the Rail, Maritime and Transport union (RMT), Aslef, the Transport Salaried Staffs Association (TSSA) and Unite are taking part in the industrial action in a dispute over pay being offered for the new all-night Tubes, which will be launched in September.

Managers have tabled a "final" offer, including an average 2 per cent rise this year, at least RPI inflation for each of the next two years and £2,000 for drivers on the new service, but this has been rejected by the unions.
