Is sub-surface Underground stock built to a wider loading loading
gauge that NR stock?

Or what is it that makes it out of gauge?

Metropolitan Railway Cars were wider at the Sole Bar than other
British main land rolling stock. =A0North of Quainton Road, Met. Cars
were out of guage towards Calvert, but within guage towards Verney
Junction. =A0"A" stock took advantage of the wider availability. =A0I
cannot speak to "S" stock.

Way back in 1907 the West Somerset Mineral Railway was briefly brought
back into use. =A0The operators used an old Metropolitan Railway Steam
loco which was brought down on the GWR and delivered over a temp
connection from the Minehead branch to the mineral line. By all
accounts it had a few bumps and scrapes with GWR infrastructure on the
way and when the short period of use on the Mineral line came to an
end the GWR is supposed to have refused to handle the Loco again and
it left by sea. So =A0Metropolitan Railway loading gauge being different
goes back a long way.

That says a lot. The GWR had a generous load guage.

According to wonkypedia the new S stock is 9 foot 7 wide which is about 5
inches wider than the class 378 NR stock on which its based, so the tradition
is being continued. Assuming the entry is correct of course.
