A person has been hit by a train causing major disruption to services in and out of London King’s Cross.
Meanwhile, a fault with the signalling system at London Blackfriars means that fewer Thameslink services are able to run across the network.
Dozens of trains are either delayed or cancelled, with the affected operators including Lumo, LNER, Thameslink, Great Northern and Grand Central.
The disruption comes after a person was hit by a train between London and Cambridge / Peterborough.
All northbound lines are currently closed out of Kings Cross St Pancras on Friday morning.
