A landslip between Three Bridges and Gatwick Airport means some northbound lines are blocked.
As a result, services may be delayed.
Disruption is expected until 15:00.
Customer advice:
Can you tell me more about the incident?
Trains are able to run trains on a different line past the landslip, but there may be delays caused by more trains than normal on just the one line. Also, we'll need to continue to monitor the safety of the railway, and if anything changes, we may need to reduce the services. You'll find the latest updates on this page, so please continue to check back here for information.
Landslips can happen for a number of reasons, including severe weather. Teams are working with Network Rail to ensure repairs at this landslip site are carried out as quickly and safely as possible.
