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?

LU surface stock goes out of gauge on curves (and thus within
platforms if using a crossover). IIRC it is not actually out of gauge
on straight track but is the only stock (apart maybe from some 3rd
rail stock from which shoebeams have not been removed ?) which will
utilise certain parts of the available gauge so that an intruding
obstruction will be missed by most NR trains but could be struck by an
LU train being dragged.
Taking a quick look at e.g. :-http://www.joyce.whitchurch.btinternet.co.uk/clear950.gif
the same might equally apply to tube trains whose floor level is
closer to the ground.

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

Way back in 1907 the West Somerset Mineral Railway was briefly brought
back into use. *The 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 *Metropolitan 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.

which has been made use of more recently. The 165s and 166s are among the
few 3+2 23 metre stock and would be out-of-gauge on many lines away from
their hunting grounds.

The Metropolitan Railway was originally built (from a junction with
the GWR at Paddington to Farringdon Street) to mixed standard and
broad gauge (7' 0¼") and was initially operated by the GWR using GWR
rolling stock. This is one reason why the Met has been able to
operate larger trains than standard.

I don't believe that the S stock is based on the 378s, which are an
Electrostar variant. Where did you read that they were? The S stock
is probably closer to its fellow Movia 2009 tube stock.

Thank you Boltar. That is useful. I believe it is also the case the
subsurface stock structure gauge is now a couple of inches shorter
than the mainline.

This has not always been the case. However, IIRC, when LUL acquired a
4TC for rail tours, etc., the roof vents had to be removed. I assume
that the track bed had risen with successive ballast replacements, or
devices have been attached to the tunnel roofs over the years.

Can't remember offhand. I think I read it in one of the railway mags.
Still, its quite wide, though with the low floors the doors curve in at
the bottom and I don't reckon that'll be a comfortable place to stand in
crush conditions. At least though they don't seem to have wasted space
with a needlessly thick filler section behind the seats like they have on the
victoria line trains.
