Can you tell me more about the incident?

Trains are likely to have some delays due to a fault with a signal in this area. In this case, the signal has been reported to be switching rapidly between different colours and not showing a steady indication to drivers. This means drivers have to stop at the preceding signal and gain verbal instructions to continue. Your journey will unfortunately take longer as a result.

Railway signals are designed to warn drivers that they have to stop because the system can't yet confirm that the route ahead is clear. In most places, the signalling system will show a green light, or aspect, when the track is clear for a long distance ahead, and drivers will then be shown one or two yellow lights to warn them when they are approaching a red signal. This means that they can anticipate the amount of braking that's required to stop before they reach another train or any form of problem on the line. In this case, as the signal isn't reliably showing the necessary indications to drivers, they'll need to take extra safety precautions to travel through the area.

The signalling system is maintained by Network Rail, Southern and Thameslink are working closely with them to diagnose the fault and make sure it is fixed as quickly as possible. Until this is done, they will be closely monitoring the train service and doing their best to keep to the timetable.
