Dozens of services between Norwich and Sheringham, Great Yarmouth and London Liverpool Street were cancelled this morning due to a combination of train and signalling faults.

Services between Ipswich and Lowestoft in Suffolk were also subject to cancellations.

The disruption comes after more than a week of problems on the Greater Anglia network which saw around 80 services cancelled across Norfolk and Suffolk on a daily basis.

The rail provider had said it hoped to be operating a more regular service from today after introducing more services to ease problems.

But commuters still woke up to extensive disruption on the operator's rural routes, including the Norwich to Sheringham line this morning.

In a statement, a spokesperson for Greater Anglia said: "We are now able to run our trains on most of our rural lines, so service is much better than last week.

"Network Rail is still asking us to run trains slower on the Norwich-Sheringham line while the level crossing investigation continues, so there is a reduced service on this line.

"We sincerely apologise to customers affected by problems last week, when we were unable to run our normal train service on branch lines due to signalling issues."

"Anyone who has been delayed by 15 minutes or more should apply for delay repay compensation.

A spokesperson for Network Rail said the speed restrictions would remain in place until it, along with Greater Anglia, had fully investigated the root cause of the recent problems on the line.

The investigations include testing the impact of leaf contamination, the level crossing mechanisms and how trains' wheels connect with the track signalling system.
