The company added that disruption is currently expected until 10am.

It added: “You should travel using your normal route, but leave an additional 10 minutes to complete your journey.

"You should check journey planners before you travel.

"If you're travelling now, you should check the Southern app and station screens and listen to announcements for the latest train running.”

This part of the network uses track circuits to detect trains. If a circuit fails, the system ‘may think a train is still there, blocking others from moving forward’, Southern explained.

During such incidents, drivers ‘must stop at red signals’ and get ‘verbal permission to proceed at a reduced speed’. This can cause significant delays – ‘especially in areas with long track sections’.
