At a glance, the wheels either side of the bendy bit seem quite far

Actually I could be confused. I think the new units (supposedly
illustrated in the diagrams) have longer bogies, or possibly just a
longer middle bogie.
I hadn't heard that the new bogies were longer. I wonder why they'd do
that, on units that have to get round very tight curves?
Conversely, in the artist's impression you posted, all four (sic)
bogies
look too short. But I'm guessing that was just the artist making that
bit up, not thinking anyone was particularly interesting in the
wheels.
I also wonder if the floors aren't too low as well in that sketch?
I will have to start paying more attention, and maybe take a snap.
Further posts may be from Belmarsh.
Yes please, of the elusive latest models, B07/09 ... which may indeed
have
4 bogies ... we shall see.
The picture he

snow-jp.jpg
shows the B07 units as only having a single middle bogie. You can see
the spots where the wheels are behind the current rail at the front,
middle and back of the unit. I doubt the articulation would work with
separate bogies and still be able to run around the sharp curves.
There's absolutely no doubt about them having a middle bogie at the
articulated point (ie three bogies per "vehicle"). The only question
in my mind now is whether they are a different length of bogie from
the earlier units. My impression was that they are, but I'm wondering
if it's some kind of illusion.
Well I looked at the image upthread, and page zoomed it up the
magnification - which becomes pixellated. It's very hard to see, but from
the positions of underfloor equipment, ISTM that there isn't room for
separate bogies under each car at the "joint".
Thanks to those who've been looking and shooting.
