Trains are running as normal through North Norfolk after a signalling fault was fixed by engineers.
Due to a fault with the signalling system between North Walsham and Sheringham, all lines between the towns were blocked earlier this evening.
Trains travelling north from Norwich were forced to terminate at North Walsham.
The problem started after 5pm, and led to initial train cancellations.
But when Network Rail engineers investigated it became clear that the problem could not be fixed quickly and passengers were advised to use replacement buses between North Walsham and Sheringham.
As a result journey times were extended to up to an hour.
Greater Anglia, which runs trains along the line, apologised for any inconvenience caused.
The problem was expected to be solved by 11pm, but engineers completed the work by around 10pm.
A good service now operates across all Greater Anglia services.
