A signalling fault has caused disruption for passengers on rail services between Norfolk, Cambridgeshire and London.
The earlier fault with the barriers at Kiln Lane, Ely and a signalling system fault caused services through the town to be suspended.
The faults has been fixed and services have resumed, but operators Greater Anglia and Great Northern said it was expecting cancellations, delays and alterations to continue "while the service recovers".
Services between Ely and Norwich, Ely and Cambridge and from King's Lynn towards London were among those affected.
