Signalling problems on the line to Cambridge means there are changes to some trains from Ipswich.
Services running between Ipswich and Cambridge are being rerouted to Ely from Bury St Edmunds because of the issue.
This means none of the eight services scheduled on this route will serve Dullingham, Newmarket or Cambridge until further notice.
No time has been given for when the problem will be resolved by.
