Can you tell me more about the incident?
A fault with the signalling system between Three Bridges and Gatwick Airport means that our usual "fast lines" are closed, and all trains will instead have to run using the "slow lines". This is a significant reduction in available lines and as such we need to reduce the number of trains running through the area.
Network Rail technicians have been working overnight to fix the fault, but unfortunately it has reoccurred. The team remains on site and work is ongoing to investigate the cause and attempt to carry out a successful fix.
