Can you tell me more about the incident?
Operators have had a report of a possible issue with the track in this area. Network Rail's engineers are attending as quickly as possible to carry out a detailed inspection.
There are various different types of defects, and the first advice usually comes from drivers or other staff travelling through the area. Response staff will check the location which has been specified and find out whether the track is still supported correctly, whether the rails themselves are in the usual condition, and if there are any problems with the fixings and metalwork which attach the rails to the sleepers.
Until this is done, trains have been stopped from running in the affected direction. This is a necessary safety precaution.
