Can you tell me more about the incident?

We've had a report of a possible issue with the track in the Crews Hill area, with the line towards Alexandra Palace and Moorgate being blocked. Network Rail's engineers are on site and currently carrying out an inspection of the track.

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.

When we get more updates from site, we'll pass them on to you.
