A signal fault is causing rail delays between Norwich and Sheringham this morning.
Train operator Greater Anglia said there had been a fault with the signalling system at North Walsham.
It said trains were having to run at reduced speeds, and services between Norwich and Sheringham, via Cromer, may be delayed by up to 15 minutes.
The 7.36am Norwich to Great Yarmouth service has also been cancelled due to the issue.
The company added that the disruption is expected to last until 10am.
