Actually, I don't know why 18 manages 12 car, but 19 is down as 8 car.
I've had longer trains that 8 coaches in platform 19. For example a
2+9 HST to Reading via Ascot during engineering work (and I think the
Eurostar connection HSTs also generally used 19); I think this went
via the Windsor reversible . The platform face for 19 goes all the way
to the end of the Eurostar platforms although it is very narrow at the
country end and it maybe that it was only checked for multiples of 4
coaches when it was surveyed.

IIRC the country end of platform 19 has "Do not alight here" signs (or
similar), so perhaps it's officially non-compliant at that end.


In that case, maybe I'll withdraw the temporary reprieve I gave to
platform 20 ... Maybe it wouldn't be structurally possible to widen
the platform by encroaching on platform 20 though.

I don't think there is any problem using at least 12 car lengths, if
approaching from the Windsor Reversible. The problems would come if
you want to run a Eurostar length train in there!!

Are you sure the HST was 2+9? AFAIK WR HSTs have never been longer than 2+8,
and the E* connection HSTs were also 2+8. A 2+8 HST is shorter (by about 1
coach) than a 12 car train of 20 metre stock (though as also posted, it
seems the platform can physically accommodate a 12-car SR emu,but the outer
end is non-compliant, presumably because it is too narrow).

Sorry, 2+9 was a typo. Just checked my records though and the Purbeck
Pioneer 1st April this year was 11 Mk 1s and 1 Mk 2, top and tailed
with class 66s. I make that 14 vehicles and so I don't think that
there is any problem with train length from the signalling point of
view!! I don't think that there were any announcements about getting
out at the rear of the train either, there certainly were at Swanage.

Ah, I wondered when that would be happening.

I'd just like to mention at this point how much fun I didn't have printing
160 A1 sets of all the drawings for that. I suppose this is what happens
when there are 16 locations where they may be inspected:
