Trains on the line between King's Lynn and London are being replaced by buses tonight because of problems with the overhead lines.

Passengers travelling between the Fens and the Capital face long delays for the THIRD DAY in a row.

Network Rail said: 'We apologise to passengers for any disruption to their journeys.

'Overhead line problems between Royston and Cambridge mean trains cannot run between Letchworth Garden City and Kings Lynn. Buses will run between these two stations.

'Our engineers are on site trying to fix the problem as fast as they can.'

Thameslink Great Northern, which operates trains on the line, warned of 'major disruption'.

A spokesman added: 'Network Rail is continuing to investigate reports of problems with overhead line equipment between Royston and Cambridge.

'Ticket acceptance has been arranged with Abellio Greater Anglia who operate trains between London Liverpool Street and Cambridge. The first service to run between Cambridge and King's Lynn is the 15:35 Greater Anglia service.

'From then on; a shuttle train service will run between Cambridge and King's Lynn every two hours. Rail replacement buses are also operating between Cambridge and King's Lynn.

'If passengers are travelling to stations between Letchworth Garden City and Cambridge, please change at Letchworth Garden City to catch a rail replacement bus that will be stopping at intermediate stations.

'Bus co-ordinators have been arranged to organise these services. All services are subject to change and short notice alteration.'

Russell Hancock, from Playhouse Yard, Downham Market, said: 'There was absolutley no communication on what is going on the ground.

'I really feel for the families with young children trying to get home, clearly nothing has been learnt from the previous day's problems.

'Not sure why they can't run trains from Cambridge to Lynn as the problem is in the Royston area. There is a staggering amount of rolling stock at Cambridge that could be used to run a shuttle but alas it's in in darkness going nowhere.'

People taking trains from London King's Cross to King's Lynn were stopped at Royston, and had to wait for a replacement bus service to Cambridge and then King's Lynn.

A 63-year-old woman from Fakenham, who wished not to be named, said: 'I was supposed to get into King's Lynn for 1.21pm but instead got here at 6.20pm.

'For the bus from Royston I had to wait two hours in the freezing cold - my feet were like blocks of ice.

'I've had nothing to drink or eat since the morning, people would push pass you to get onto the replacement bus and the customer service hasn't been helpful.

'I've missed the last bus to Fakenham and if it wasn't for my step son who can pick me up I would be stranded here with no money.'

Ryan Taylor, 32, from King's Lynn, diverted to London Liverpool Street from London King's Cross, caught a train to Cambridge before getting the bus to King's Lynn in a journey which took four hours longer than intended.

He said: 'It's crazy how these problems have been left like this over the busiest travelling period of the year.

'I didn't have to wait long but it has been such a rush around today but we should be able to claim our money back.'

One woman, who refused to be named, said she saw 'little point in getting a refund' as she will have to pay a £10 administration fee to refund her £35 ticket from London King's Cross.
