Travelling on the Rhymney to Cardiff line at rush hour on the Valleys lines is a grim experience. I know that from journeys I’ve taken myself, and the Valleys lines generally, I’m told, are the same. Arriva have told me several times that there is simply no rolling stock available to ease the overcrowding. They told me that a new diesel train would take approximately three years to procure from the procurement to the receipt of the stock. That means that, if new diesel stock is ordered as part of the new franchise agreement, rail passengers may not see new carriages until 2021 at the earliest. What is the Welsh Government currently doing to ease the problem in the short term with regard to rolling stock? Moreover, is there any way the Welsh Government can order new rolling stock today or in the coming months? The new operators, when they take over the franchise, may have rolling stock of sufficient quality and number to ease the overcrowding problem.
