Can you tell me more about this incident?

Points are moveable sections of track which can send trains onto different routes at junctions. These are part of the signalling system, generally managed by Network Rail.

Points can stop moving correctly for a number of reasons. For example, there may be an obstruction in the moving parts, or the electronic control systems may have developed a fault.

There are various backup systems which allow signallers to try to "set" the points, and in some cases, the points may be available for trains in one of the directions they serve, but not another. However, with more severe failures like this one, the route is blocked entirely.

Network Rail have sent their specialist Signalling & Telecoms teams to site as a priority, and they will set up a safe method of working on the track. As soon as it's safe to go on the line, they will diagnose the fault and find any quick solutions to resolve it.

Whilst this is being done, Southern / Thameslink will be monitoring progress closely. At times, replacement parts may be needed, or specialist advice from suppliers, which is why some points failures take longer to resolve than others.
