I thank the Minister for his answer. What I have noticed is an increase in concerns of poor service on the Cambrian line in particular, on the Aberystwyth to Shrewsbury line. Passengers are frequently asked to change unexpectedly at Shrewsbury due to the numbers of units used for a through service. Now, as I've understood it, there are only 21 units currently available to operate on the Cambrian line—which I know the Minister will know has a unique signalling system—and services are often cancelled because of the lack of available units to cover mid and north Wales. The new trains proposed, as the Minister has outlined, will replace older units like for like, as I understand it, but won't increase the number available to operate the overall service. So, can I ask what the Government is doing to increase the number of units overall to provide an adequate train service for passengers on the Cambrian line in particular, and for any update you can provide on the hourly train service? Thank you.
