St Albans commuters are facing delays and cancellations this morning due to an overhead wire being damaged between St Pancras International and St Albans.

One of the northbound lines between St Pancras International and St Albans City is blocked because an overhead wire is damaged in the Cricklewood area.

Thameslink tweeted that services to and from St Pancras International and St Albans may be cancelled, delayed by up to 30 minutes or revised.

Northbound services between West Hampstead and St Albans will be reduced to one train an hour.
