There was much on the news last night about the £500M revamp at
Victoria and the increse in capacity. Surely you can only increase
capacity buy increasing the frequency of trains or increasing the
carrying capacity or have I missed something.

I had the same thought - I think there are only four platforms for
Victoria and Circle/District. and most people won't want Victora
southbound...

I don't know about the District/Circle but the Victoria lines platforms
are already packed to overflowing. How is increasing the passenger
tunnel capacity going to help. I would have thought that £500M would
have been better spent incresing train length to give extra capacity
which would also help in loading unloading times therefore increasing
frequency.

London Underground can't increase length (despite the election
promises of the new Conservative MP for Putney) because the length of
the platforms in subsurface tunnels is fixed. To lengthen all the
platforms would either be prohibitivly expensive, or take so long as
to take generations to actually build.

Much as it might pain me to agree with her, the new MP for Putney is
not wrong. The District Line ran 8-car Q, CP and R stock trains until
the 1970s. The platforms, give or take a bit of selective door opening,
are all long enough, except between High St Ken and Edgware Road where
shorter trains have always been used. So, if the eventual D stock
replacements were 8 car length (car lengths as C and earlier stocks)
there would be a worthwhile increase in capacity.

Fair point, but that would involve re-arranging the timetable/line
permutations because of Wimbleware, so if you're throwing that kind of idea
around, I guss anything's possible!
