Can you tell me more about the incident?

It has been reported that a road vehicle has struck a railway bridge in the Stevenage - Herford North area.

This means that trains have been stopped on all lines which travel under the bridge, so your train won't be able to travel on this route at the moment. Network Rail will be sending engineers as quickly as possible to check the bridge for any damage, and if it's safe to do so, the route will be reopened.

Great Northern take railway safety very seriously and need to make sure it's safe for services to run as planned.

If you see a vehicle hitting a bridge, or you think a bridge has been damaged, please report it using the phone number on the identification plate fixed to the bridge. If no plate is provided, please report it to the police by calling 999.
