Trefnydd, I'd like a written statement, please, on rail infrastructure funding. I'd like to know how much money has Wales lost over the years due to the delay in the electrification of the Great Western rail line, the fact that HS2 and probably the Northern Powerhouse rail are classified as England-and-Wales projects. Last week, I raised during First Minister's questions the upgrading of the Cardiff west junction in Canton to enable four trains an hour to run through all Cardiff stations. This is the responsibility of Network Rail and UK Government. Since then, it has been pointed out to my office that this originally was included in the Department for Transport Network Rail Cardiff area resignalling and renewal project 2012-15, but, for whatever reason, it didn't happen. They said they were going to do it between 2012 and 2015, but we're still waiting in 2023. Can we please have it set out how much we have missed out on and why we are missing out on this money? The answers we're receiving back from the UK Government are becoming more and more weak, and that is to put it mildly. Diolch yn fawr, Trefnydd.
