Trains running through Ipswich are being cancelled or delayed after a signal fault.
Two services between the town and Felixstowe have been cancelled, while other trains passing through are facing delays of around ten minutes.
It follows disruption elsewhere on the network this morning.
Earlier this morning services in and out of Norwich were delayed by a points failure – having a knock-on effect across the rest of the region.
Other trains between Ipswich and Lowestoft have been cancelled or replaced by a road replacement service due to a points failure, while the 7.03am service from Stowmarket to London Liverpool Street did not run due to a train fault.
Operator Abellio Greater Anglia apologised for any inconvenience caused.
