Problems with an overhead wire at Diss have been fixed.
Passengers earlier today faced delays and cancellations to their train due to the problem, and train operator Abellio Greater Anglia said tickets could be used to travel via Cambridge from London King's Cross.
But services are now running as normal.
There had also been problems on the Norwich to Lowestoft line, due to 'urgent repairs to the track at Oulton Broad North', but these have also been fixed.
Abellio apologised for the disruption.
