Train users between Norwich and London Liverpool Street were tonight (Wednesday) facing delays because of problems with signals.
National Express East Anglia said that signalling problems were causing disruption between Witham and Kelvedon and near Stowmarket and delaying trains by up to 30 minutes.
The rail company said the delays were likely to continue until about 11pm.
