Had a look around the mock up train at euston the other day. Whatever
happened to the walkthrough train concept they were promoting a few
years back with cars joined by a gangway? I also remember some
silliness over overhead line pickup too but unsurprisingly that seems
to have disappeared into the daft ideas bin. From the mockup I'd say
it looks pretty much the same as the interiors on the northern and
jubilee lines with the same narrow windows. Bit disappointing.

Anyone have any tech specs for these trains? I've tried to google
but nothing about the powertrain or electronics comes up. Also , what
type of signalling will be used? Will it be the same as the jubilee
system
or will it be yet-another-new-incompatable-with-every-other-line
system as per LULs apparent standard approach these days?
