A train company has been criticised for offering customers "poor value for money" although passengers are happy with improvements to punctuality.
Value for money offered by One has been criticised
A national survey by rail campaigners Passenger Focus reveals people in the East using One Trains are unhappy with their ticket price structure.
Overall satisfaction had dropped since last year with only 41% of passengers believing tickets gave good value.
One's public affairs manager Peter Meades said there had been problems.
He said: "On our West Anglia routes the performance has not been particularly good and we have had difficulties with a timetable change.
"Performances through the autumn were generally not good either and perhaps this was uppermost in people's minds.
"On top of that, the work we have done in upgrading trains was only coming into play late last year so we did not benefit from that in the study."
The operator provides train services between London, Norfolk, Suffolk, Essex and Cambs.
Passenger Focus, the new name for the Rail Passengers Council, surveyed 26,000 people across the country earlier this year.
It found less than 30% of One passengers thought they were getting a good deal, while only 40% of people on c2c trains between London and Essex felt that way.
A Passenger Focus spokesman said customers felt "perplexed" by long-distance pricing systems and that value for money had become the a problem for the industry.
