Among those services affected are the 5.38pm service from London Liverpool Street to Ipswich and the 5.50pm train from Liverpool Street to Norwich.
Work is currently taking place to fix the problem.
A Greater Anglia spokesman said: “We thank you for your patience and understanding whilst this problem is being fixed.”
