A Norfolk MP has criticised Network Rail for affecting Greater Anglia's line as the train service's performance dropped to an all-time-low.
North Norfolk MP, Norman Lamb, obtained railway figures for 2018 showing that the Greater Anglia franchise suffered its worst year with 3.64pc of trains being cancelled.
Of those that did run 87pc arrived on time.
Mr Lamb said: 'It's hugely disappointing to see record cancellations on the Greater Anglia franchise.
'Depressingly, this poor performance is not unexpected. The figures make clear that the delays are being caused disproportionately by infrastructure, which is managed by Network Rail.'
He has called on the Department for Transport and Network Rail to urgently address this under-performance which causes such disruption to passengers.
But Greater Anglia said performance is on the up.
A spokesman said: 'Performance is improving – on many of our Norfolk routes punctuality was well over 90pc in January and that trend is continuing in February. However, we know that customers want punctuality across the network to be consistently better. We have regular 'performance summits' with Network Rail to ensure that together we deal with delays more quickly, both in terms of fixing what has gone wrong and then getting the railway running back to normal quicker.
Network Rail says it is investing £2.2bn in the region in the next five years.
Meliha Duymaz, Network Rail's route managing director for Anglia, said: 'We know that train punctuality for Greater Anglia customers has not been what they expect or deserve over the last 12 months.
'We take full responsibility for the part we have played, and we have been working with Greater Anglia to address the declining trend in punctuality in the short-term.'
