A fault with the signalling system between Norwich and Stowmarket caused delays and disruption to train services on the line on Friday.
Greater Anglia said at 7.50pm that all lines had reopened following the fault, but that trains running between Norwich and Ipswich may still be cancelled, delayed or revised.
The disruption had ended by around 9.30pm.
