Minister Lee Waters defends going to train unveiling by car
Wales' train services will improve "gradually" over the next few years, the deputy minister for climate change said.
Lee Waters unveiled the first of 70 new trains to be used on the South Wales Metro, which is expected to be completed by 2023.
He also defended travelling to the unveiling by car, saying he did not have "a normal job".
It comes as the chief executive of Transport for Wales said he was "not happy" with some commuters experiences.
Natasha Asghar, the transport spokeswoman for the Welsh Conservatives, said commuters had been rammed on to trains "like sardines" and were "disgusted".
