If apparently the 09 stock did get dragged through the piccadilly line

09 and other tube stocks can we? Maybe a few centimeters one way or the
other at most which surely wouldn't make much difference to equipment?

Thats what people on here were saying. I've no idea if its true. But it
occured to me that the victoria line uses an old piccadilly line tunnel on
the northbound at finsbury park and I very much doubt they would have
bothered to spend a fortune to enlarge it by a few inches so as 09 stock
has to fit through it must be pretty close to standard tube gauge.

Isn't it more to do with the bends rather than the diameter?
