Yes, it's true. They're a couple of inches taller and each train is a
few feet longer.

My understanding, based on things i've read about the JLE, is that the
speed at which a train can run is limited in part by the clearance between
the train and the tunnel wall - for aerodynamic as much as kinematic
reasons. Does this mean that the new obese Vic trains won't go as fast?

Trains rarely need to leave their home line, though I have heard talk of
seeing if they can be squeezed down the Piccadilly Line.

Is there a connection to the West Anglia at Northumberland Park?
Presumably, even a chubby tube train is smaller than NR gauge. Don't know
if you could run to anywhere useful from there, though.
