The transport Minister's been indicating to me during your contribution that he is happy to provide an update to Members on the issues that you raise, but I do know that Transport for Wales are very aware of the capacity issues, particularly on the Rhymney line, and they've been exploring options to address the issue. 

Since taking over the franchise, it's fair to say there's been increasing demand on that line, and I would expect probably above and beyond that which was predicted. So, Transport for Wales are currently exploring how to improve that customer experience, and they've done so already, to a degree, by introducing those extra class 37 transition peak services in May of 2019.

Transport for Wales are fully reviewing all of their passenger number forecasts, and they assure us that the service they provide in 2023 will meet those demands, as many options are currently being considered and planned. But, as the Minister said, he'd be happy to provide an update that addresses your concerns.
