From
the BBC» The boss of Transport for Wales has admitted he understands passengers' frustration as TfW marks the first year of running the nation's rail services.
Overall, 82% of passengers are satisfied, the same as 2018, according to the latest official survey.
But travellers reported seeing an improvement in how delays have been dealt with since TfW took over from Arriva Trains Wales.
"We've tried very hard," said TfW chief executive James Price.
He recognised there was frustration at the pace of change, with operators "playing catch-up" after damage to trains in last autumn's storms.
TfW brought in trains from elsewhere to plug the gaps, although there will be delays in bringing in 10 new four-car trains for the valleys lines.
