Thameslink and Great Northern trains between London and Peterborough or Cambridge ran via Hertford.

Trains between London and Ely or King's Lynn only ran as far south as Cambridge, and did not travel to London.

Stopper trains between Cambridge and London King's Cross, via Royston, ran between Cambridge and Welwyn Garden City only.

Some trains could not stop at Hitchin.

"If you require Hitchin, please travel on to Stevenage, and travel back to Hitchin on a train in the opposite direction," a Thameslink and Great Northern spokesperson said.

LNER said some of its trains were delayed by around 20 minutes due to the disruption.

Passengers on LNER trains also faced delays between Grantham and Newark North Gate due to safety checks, the company said.

LNER said its passengers could travel on Thameslink or Great Northern trains at no extra cost.
