It seems air track could justify 12 carriage trains running out of the
old international platforms at Waterloo.

What else is planned for them?

It is said that platform 20 may be used by SWT for Windsor line services
from this December, when the new timetable starts (although that was
supposed to have happened last December).

The other platforms will come back into use when SWT extends to 12-car
trains on the Reading line (and 10-car on suburban services), but this
won't be until 2012-14 because of infrastructure changes needed at the
station throat. I suspect that that will result in a period of severe
disruption at Waterloo, given that the approach tracks are already one
of the main pinch points on the entire SWT system. No pain, no gain ...

I would have thought that the main work would be moving several
crossovers so that trains on the up main could get beyond platform 15,
and corresponding shifts towards the north, or else congestion would
be worse than ever with lots more use of crossovers further down the
track.

Also, I wonder if it would make sense to take platform 20 out of use
so that 19 could be extended?

Do you mean take platform 18 out of use? Platform 19 already has track
the full length of the platform face and the track is actually
slightly longer than platforms 20-24. However, it has a crossover two
thirds of the way along allow access from the Windsor Reversible to
platform 18.-

Oh right, maybe I'm out of date or confused.

I thought 19 was only eight coaches long because there was no platform
against the back of platform 20 at the country end. *If it's only
because of the crossover ... or if it isn't really restricted to
eight ... *Now I can't work out how 18 manages to be longer.

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.
