Thameslink services are currently disrupted due to an incident affecting travel between Stevenage and London Kings Cross. The incident was first reported at 7:25 am on March 17, 2026, leading to significant delays for passengers.
Trains are running through the area but at reduced speed, resulting in expected delays of around 30 minutes. Passengers are advised to check the latest travel updates before setting out, as alternative travel arrangements are in place, with tickets valid on Thameslink and Great Northern services.
In addition to the disruption between Stevenage and London, signalling problems between Peterborough and Grantham have also affected journeys to and from London King’s Cross. All lines are currently blocked due to this signalling fault.
Thameslink services between St Albans and London resumed after a tragic incident that forced the line to close overnight. The blockage on the line from St Albans City to West Hampstead Thameslink was reported at around 9:00 pm ET on March 15, with emergency services attending the scene.
As services begin to return to normal, a spokesperson noted, “There may still be some residual delays, cancellations or last minute alterations whilst service returns to a booked timetable.” Customers who have not yet started their journeys are being strongly advised to avoid travelling if possible.
Compensation may be available for delayed journeys, and passengers are encouraged to keep their tickets and note their journey details if making a claim. Support is also available for those emotionally affected by the incident, including a helpline number provided by Thameslink.
Thameslink stated, “Services are returning to normal between West Hampstead Thameslink and St Albans City following this tragic incident.” If you or someone close to you has been affected by this or any incident, there is always someone to talk to.
The incident caused significant interruption for journeys scheduled around the time of the incident, impacting many passengers’ travel plans.
