Generally I like the big infrastructure projects I'm currently working on one, but I'm not sure of the value of this project, our railways are Victorian and desperately need an upgrade, but all this dough just to get to London quicker ?, money should be spent but over the entire network and not just on one project, slightly off topic, and as a regular user of the local trains, IMO valley lines have become a poorer service after the recent franchise change. The information board at heath high level into Cardiff side has not been working for months and the ticket machine has been dodgy for 3 weeks at least, maybe it works in the week but it hasn't been working on Saturday's.
