North West Norfolk MP Sir Henry Bellingham.

North West Norfolk MP Sir Henry Bellingham is seeking reassurance there will be no delay in the introduction of eight-carriage trains to and from King’s Lynn.

Sir Henry has written to Govia Thameslink Railway in light of a recent National Audit Office (NAO) report which concluded Govia Thameslink had failed to bring forward new rolling stock on some of their lines.

The report found that between September 2014 and September last year, passengers on the franchise experienced some of the worst service performance on the national rail network.

Since July 2015, around 146,000 services (7.7 per cent of planned services) had either been cancelled or delayed by more than 30 minutes, compared to 2.8 per cent on the rest of the network.

Sir Henry said: “Although this mainly concerns Southern Railway, I am worried that Govia’s distraction elsewhere could lead to delays in their critical commitment and promise to run eight-carriage trains through to Lynn by December this year.

“After all, we have been told that as of this spring the journey time from Lynn to London will increase a little.

“Govia always countered by pointing to the arrival of longer trains later this year, plus also the prospect of the half hourly service that is due to be started once the Ely North Junction engineering work has been completed.”

The MP said he was seeking urgent assurances from Govia Thameslink Railway there would be no delay in the introduction of the promised eight-carriage trains, because it was such a vital issue both to constituents and the local economy.

Last week Sir Henry and South West Norfolk MP Elizabeth Truss gave their backing to the new Love West Norfolk campaign to promote the area.

Ms Truss said how important it was for the two of them to work together and continue to push for improvements to the Ely North Junction. The multi-million pound upgrade  would bring improvements for passengers, see more regular trains to King’s Cross and boost the local economy.
