East Midlands Trains are suspended this morning between Luton and London St Pancras because of overhead wire problems near Hendon.
Trains are not expected to run to St Pancras until about 1pm today (Friday, January 17), so that the damage can be assessed.
Tickets are being accepted on London Midland, Virgin Trains, East Coast and CrossCountry services.
Shuttle buses will be running to take passengers to connect at other stations.
Services are also suspended on First Capital Connect between Luton and St Pancras International due to the overhead wire problems at Hendon.
