What is the problem at Wembley Park?

I've noticed that the Met has been showing delays owing to a track fault at Wembley Park and all trains were semi-fast when I was at Baker St. Presumably it is a problem with the points. Does anyone know what the problem is and when it is likely to be fixed?

I think there have been a few problems with those points in recent years.

Yes, there is a points failure at Wembley Park preventing trains from Finchley Road from accessing the local line at Wembley. All trains from the city are running semi, with the usual Baker Street service reversing via Neasden depot instead to ensure a service to the local line stations.

It will be ongoing for a few more days at least, largely due to Night Tube-related access reasons.

It is not a points failure but a track defect (cracked crossing) meaning that the points can only be used in the normal position (ie. trains coming out of the depot).
