I'd like to thank the Member for his question and say that the feasibility work is being undertaken at the moment. I believe it will be concluded in the new year. The UK Government is, of course, still responsible, unfortunately, for funding railway infrastructure in Wales. However, the feasibility study, once complete, will be used to inform Network Rail's, and indeed the UK Government's, planning process for rail infrastructure, and I am pleased to have been able to support this feasibility study. The Member highlights numerous benefits from upgrading rail infrastructure across Wales, including the potential of the Aberystwyth-Carmarthen railway line.
