Can you tell me more about the incident?

Earlier this evening, the 16:19 Sutton to St Albans City service developed a fault in the tunnel section between London Blackfriars and London St Pancras International, blocking the northbound line through City Thameslink and Farringdon.

Onboard crew, fleet support teams, and Network Rail responders worked together to rectify the fault and safely move the affected train clear of the running line.

All lines through the core have now reopened. Because trains were held behind the blockage during the evening peak, residual delays and minor alterations will continue while the timetable settles back down.

You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
