The truth is the Welsh Governement through Transport for Wales took all the big decisions anyway. The railways were run by a Civil Servant. Keolis Amey were really unhappy that Keolis Amey (Transport for Wales Rail) that they got the blame when things went wrong and the WG tried to take credit when (rarely) something positive happened. Most insiders belieive that Keolis Amey would have pulled out anyway at some point. To be truly effective they now need someone who is not a Civil Servant to run them.
