Some train services between Norwich and Diss have been cancelled because of a broken rail - with replacement buses ordered.
Greater Anglia tweeted at just before 9am that some lines were blocked due to the broken rail.
The 8.30am and 9am trains from Norwich to London Liverpool Street were cancelled. The 11am and 11.30am London Liverpool Street to Norwich service has also been cancelled.
Network Rail engineers are on site investigating the issue.
Some services are running, but at a reduced speed.
Greater Anglia said rail replacement buses, operated by Galloways, Simons, Angies and Norfolk Norse, would run between Norwich and Diss until 10.30am.
