The disruption is being experienced to Gatwick Express and Southern journeys to and from London Victoria, as well as Thameslink services through Streatham.
Passengers are being advised not to travel to London this morning as there is a very limited service and trains will be extremely busy.
A major fault with the signalling system has been affecting Southern, Thameslink and Gatwick Express train services since 10.30pm last night (Wednesday July 4).
The signalling fault is affecting one of Govia Thameslink Railways busiest mainlines and rail companies are actively working with Network Rail to resolve the fault as quickly as possible.
A statement on the Southern websites says: “Network Rail engineers have been working throughout the night to rectify the signalling issue, however this has been unsuccessful so far. Engineers will continue to work throughout the day with all available resources to resolve the fault.
“The root cause of the fault has been traced back to a power supply feed, linked to the signalling equipment which has failed. A generator has been sourced to isolate the power feed and is expected to arrive at the signalling centre later this morning. Once the generator arrives, the situation will be re-assessed.
“We anticipate disruption will continue until the end of service.
There is a very limited service running across the Southern, Thameslink and Gatwick Express network.
This incident also affects Thameslink services between Luton and Wimbledon which have been suspended until further notice.
