With non-articulated stock with conventionally spaced bogies, there's a
lot of relative movement at the car ends on entry to curves, which the
gangway bellows have to absorb. This makes them thicker, and reduces the
gangway width. The same is true in vertical direction. So if you were to
try and install open gangways on a train like the 2009 stock, the
gangways would be very very cramped (narrow and low).

The curves are very gentle on the victoria line except perhaps in the depot
but that wouldn't matter since there wouldn't be any passengers on board then.
