There was a short piece on BBC london news on TV last night about
the new vic line trains and an interview with some bod at (I
think) Bombardier. Anyway , turns out that it looks like the
prototypes at least will have less seating (quelle surprise) and
a lot of what seating is left will be flip up so theres room for
all these mythical wheelchair bound passengers we keep hearing
about but no one has ever actually seen.

But how does this new train design compare to other (relatively)
recent tube train designs? Have they overcome the following three
design flaws:

Floor too high?
Wasted space between seats and wall?
End connection not safe to use while train is moving?


The end connection will never be safe to use while the train is
moving, simply because the ends of the cars do not remain in
alignment. Watch them going round bends, in some cases the door on
the adjacent car is completely obscured.

However, the new subsurface stock will (apparently) be truly
articulated.

Depends what you mean by articulated. They certainly appear to have
near-full-width inter-car gangways. However, the word 'articulated'
tends to be used to mean that one bogie is shared between two cars, as
in the original "space-train" concept for the Victoria Line. However,
that's not necessary to achieve wide inter-car gangways.

I'm not sure why this can be done on the SSL stock and
not the Victoria stock (for which it was originally proposed).

Nor am I, though I suspect it's a cost and operational choice rather
than that it *can't* be done.
