Can you tell me more about the incident

Your journey is likely to be disrupted by a complete failure of the signalling system in this area. The signals on the affected part of the network will have changed so that they are only showing red lights to drivers. This means that trains are unable to travel forward on any line. Thameslink won't be able to provide you with a train service at the moment.

The scale of this issue means that it could be a challenge to give you an estimate for the delays. Thameslink are working closely with Network Rail, who manage the signalling system, so that they can get more details. Their staff will be investigating as quickly as possible.

Complete signalling failures can be caused by a number of different problems - for example, power issues, cable faults or significant weather events. Sometimes there can be multiple faults which contribute to the same incident. As this type of failure is so disruptive, fault-finding and repair work will be given a high priority.

Compensation:
