They are very different trains, and because of the new design, the approvals process will take longer.Hi all, I have been following this thread for a couple of years now, though unlike Avanti's 800s that have been on the mainline, there's been little to nothing about EMRs 810s. If they are introducing 33 of them, surely there isn't room in the sheds to hide all of them. How is it that their introduction (in any stages) is so slow?
