People keep mentioning how wide A stock is , but according to my LU
rolling
stock book , A stock is 9 foot 8 inches wide whereas C stock is 9 foot
7 inches
wide (and that apperently can go anywhere on the sub surface lines) so
we're only talking half and inch either side. I can't believe the
clearances are so tight
in some of these tunnels than 0.5 inch makes a difference! There must
be some
other reason.

How long are they both overall, and where are the bogie centres ?
Can't find my own stockbook, but that could make a big difference to
how far they swing out on curves. And the restriction does only apply
on St. Mary's Curve, which is noted for being tight.
