Yes, it's true. They're a couple of inches taller and each train is a
few feet longer. Trains rarely need to leave their home line, though I
have heard talk of seeing if they can be squeezed down the Piccadilly
Line.

Ah, so is it maybe more to do with the tightness of bends rather than
the width? Would the 1973 stock already not be able to get round,
say, the Bakerloo, which is very bendy?
