Abellio Greater Anglia train
Rail passengers face delays on trains between London Liverpool Street and Norwich this evening.
Delays to main line services are down to a fault with the signalling system between Stowmarket and Diss.
It means trains are having to run at reduced speed on all lines and may be delayed by up to 10 minutes.
Disruption is expected until 8pm.
The problem is affecting train services in both directions between Stowmarket and Diss.
Abellio Greater Anglia has apologised for the disruption and said that Network Rail engineers are working as quickly as possible to resolve the problem and restore a normal train service.
