There's a comment there: "Stadler units are popping up all over the uk now and this is what can be done."
But they're not appearing over much of it, are they?
Of course they are! They're in service in both London and not-London, the two regions of the UK
The serious answer - Anglia and the GEML first, now South Wales, Merseyside next week, and Tyneside to come... plus a non-zero chance of some appearing in Scotland in future depending on how the BEMU tender works out. I agree it's not
much, but at least there's something of a decent spread.
I do wonder whether recent high floor trains will end up falling foul of updated accessibility rules in their lifetimes.
It's not at all inconceivable, in the sense that level access might become a mandatory requirement in some future update to the accessibility rules, and in my opinion it's very definitely something that we should be working towards. Probably a topic better suited to a speculative thread, though.
