Can you tell me more about the incident?
A signalling fault known as "route locking" is causing disruption to your journey in this area.
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. Track circuits 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.
In the case of track circuits at junctions, this means the points cannot be moved, as there could still be a train present. As a result, the junction will become route locked. The junction will then only be able to be used for trains running on the route which was selected when the system failed.
Until the track circuit clears, it won't be possible for your train to pass the area as usual, and if the route is locked, it may mean your train cannot reach its normal destination. Because this type of fault can result in a queue of trains waiting to continue, even if your own route is open, there can still be disruption to your journey.
Network Rail staff will be attending as quickly as possible to resolve the fault and make sure all of the affected trains can move.
Ticket flexibility:
If your train is cancelled, you will be able to travel on an alternative service operated by any other participating train company, either two hours before or two hours after the original departure time of the cancelled service, in order to reach your destination.
If you decide not to travel or cannot complete your journey due to cancellations, you are entitled to a full refund from your original point of sale.
For further information and guidance please contact your train company or speak to a member of railway staff.
