Can you tell me more about the incident?
In this particular situation the fault has been confirmed as a 'track circuit failure'. This means the signalling system is unable to automatically verify if the next section of track past the affected signal is clear.
The rail network is designed so that if a signal stops working, trains will stop before they reach it. Whilst this issue is ongoing, train crew will stop at the affected signal and contact the signalling centre to confirm their location. At this point the signaller will verbally authorise the driver to continue towards the next signal. This process adds time to every train's journey, which means services can experience short delays.
