This morning I've seen a three-unit train running on the DLR, with
the designation "Special", in between other services.

(Am I the only one having trouble perceiving the "articulated
vehicles" as anything other than units of two coaches?)

Like any other articulated vehicles (particularly trams), the short
coaches share a bogey. The only mainline trains with this
configuration in the UK are Eurostars, but they're quite common
elsewhere.

The diagrams and photos I have seen seem to me to show 2 car bodies
and 4 bogies per unit. Was I looking at the wrong images?

If you mean diagrams like this one
http://upload.wikimedia.org/wikipedi...20080224151715!...
then it would indeed appear to be wrong. *Maybe the wheels were added
as an afterthought?

It's obvious that the artist got carried away. This is a more accurate
drawing of the current stock:http://media.photobucket.com/image/d...pictures/astoc...

Except that the scale is all wrong, with tiny bogies entirely below
the skirts. It's the skirts that are the main problem, because only
the bottom of the wheels is visible below the skirts that cover the
bogies.

One can only assume that they are attached to bogies, but there are
definitely six axles per unit.

At a glance, the wheels either side of the bendy bit seem quite far
apart for a single bogie, but no further apart than the pairs at the
outer ends. I think it's probably an illusion caused by the smallness
of the wheels.

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.

Sigh ... I meant supposedly illustrated in the diagram I found, not
the one you found of the earlier kind.

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.

No, they haven't, but the middle or all may be longer.

Is this based on observation, personal .... or third party?

Still, would like to see pix, whenever .....

The picture he

http://www.railfaneurope.net/pix/gb/...u/B07/a1n-dlr-
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.
