Overcrowding can make it an unpleasant experience on a train. I heard from a member of Plaid Cymru's team here in the Assembly earlier, as it happens, about trying to travel down on the train from Maesteg to the Barbarians' game over the weekend, and passengers couldn't get on the train because trains were full. My own daughter was telling me of a journey across the north Wales line in the last few weeks where people were standing in the toilet because the train was overcrowded. It's not acceptable.
