The train line between Norwich and Diss has now reopened, after overhead wire problems shut the section both ways for most of this morning.
Network Rail closed the line both ways between Diss and Norwich at 9am, and it reopened shortly before 1.30pm.
The closure meant that a replacement bus service was operating between the two stations and adding delays of 45 minutes to services from Norwich to London Liverpool Street.
The 1.30pm service to London Liverpool Street this afternoon was the first train to travel through the line between Norwich and Diss.
During the disruption, operator Great Anglia ran a reduced train service between Norwich and London Liverpool Street, running at an hourly frequency with extended journey times.
Customers to and from Norwich were advised to travel via Cambridge and First Capital Connect services to and from Kings Cross and arrangements were made for Greater Anglia rail tickets to be accepted for these journeys on First Capital Connect and East Midlands Trains.
