Train disruption caused by a refuelling fault has come to an end but commuters have been warned a signalling fault will continue to cause problems for services via Sheringham until the end of the day.

A fuel pump fault at Greater Anglia's Norwich depot caused a number of services between Norwich, Great Yarmouth and Lowestoft to be cancelled or delayed on Friday morning.

The fault meant the operator's diesel trains were unable to be fuelled, and left trapped in the Norwich depot.

Services to and from Sheringham were also affected, and customers also advised not to travel.

The disruption at Sheringham, which is seeing trains run at reduced speed, is expected to continue all day.

Disruption on the other lines saw trains cancelled, delayed by up to 15 minutes or suspended.

Speaking on BBC Radio Norfolk, Juliette Maxim from Greater Anglia, said: "Two of the lines are operating now, the rest should be up and running by 8.30am.

"The big problem at this time of day is that all the busses are taken up on the school run so to suddenly try and get busses to supplement our train service at that sort of time in the morning is actually very difficult which is why we are advising people on the Norwich to Yarmouth and Norwich to Sheringham line not to travel, or to make other arrangements."

Shortly after 10am Greater Anglia tweeted to say disruption caused by the earlier fuel fault had come to an end but the operator also warned an earlier signalling fault at Sheringham would continue to cause problems throughout the day.

Trains between Norwich and London were unaffected.

Issuing an apology for the disruption, a spokesperson for Greater Anglia said: "We are very sorry for this morning's disruption to branch line services caused by a broken fuel pump at Crown Point depot, which meant that we were unable to refuel our diesel trains.

"Our engineers worked overnight to fix the problem and are still investigating what caused the fault. Overnight, they managed to get the pump working manually - however, this meant that it took a lot longer to refuel our trains, which led to cancellations as not all trains could be refuelled in time for the start of service.

"With further work the pump has now been fixed, allowing us to refuel trains automatically again which is a lot quicker and will enable us to restore services to their normal scheduled timetable as quickly as possible.

They said although the disruption the finished passengers should continue to check Twitter or the Greater Anglia website for information about their journey.

"Once again, we apologise unreservedly to passengers for the inconvenience caused and would encourage them to apply for compensation through our Delay Repay scheme," they said.
