Train services through Stowmarket were disrupted on Sunday morning due to engineering work not being finished on time.
Train services running through the station were subject to cancellation by rail operator Greater Anglia until 9.30am.
The company announced that trains were unable to run between Ipswich and Norwich, and Ipswich and Bury St Edmunds.
"Greater Anglia and Network Rail are sorry if your journey has been affected by this disruption," said the firm.
