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!!
