A fault with the signalling system between Selhurst and East Croydon means fewer trains are able to run. Some services running between these stations may be revised to run between London Bridge and Selhurst only.
This is expected until 08:30.
Customer advice:
Services that usually run between East Croydon and London Bridge (stopping services via Selhurst, Streatham and Peckham Rye) will run between Selhurst and London Bridge only. East Croydon will not be served.
If you are using these services and are travelling to / from East Croydon, you'll need to change at Selhurst for alternative train connections to / from East Croydon.
You can travel using your normal route but we'd advise allowing an extra 15 minutes to account for this.

Can you tell me more about the incident?
A track circuit failure in the East Croydon area means that Southern are running a reduced number of trains.
This part of the network uses track circuits to detect the position of trains. These are electrical systems which monitor whether a train is on a section of track. They operate as part of the signalling system, which is designed to be "fail safe".
When a track circuit fails, the signalling system will interpret this as a train remaining in place, even though there may not be a train present at all, or the previous service may have long since left the area.
As a result, further trains cannot be automatically allowed onto the relevant section of track. Train drivers will be stopped by red signals on approach. They will then get verbal permission from the signaller so that they can proceed, and will run at a heavily-reduced speed as far as the next signal. This is so that the drivers will stop safely if they see anything ahead of them.
In some areas, the sections between signals can be several miles long, so this can result in delays building up. Even with shorter sections of track affected, there would still be a delay of at least a few minutes to each journey.
Track circuit faults can be caused by a number of different issues, including electronic faults or obstructions on the track. Network Rail manage the signalling system, including track circuits, and their staff will be investigating as quickly as possible. We're closely monitoring progress updates, and we'd like to thank you for your patience.
