Norwich signal fault hits rail services
A signalling fault caused disruption to train services from Norfolk to London through Suffolk, Essex and Cambridgeshire on Friday morning.
Network Rail said the fault was detected at about 06:30 GMT and meant only a limited number of platforms could be used at Norwich rail station.
A spokesman said engineers have now fixed the problem.
Greater Anglia warned passengers that services would be delayed by up to an hour but they are now back to normal.
