No-one's yet mentioned the TfL 5-year £10bn investment programme,

Reading one of the news sites, someone complained that Crossrail and
Thameslink 2000 weren't included - but since Crossrail is being arranged
separately and TL2K isn't a TfL project, I don't think this is something
to latch on to desperately.

Most projects in the Plan have been announced before, but there are a
few items of interest:


well precisely. The biggest disappointment is that there is nothing very
radical in terms of pushing the bus network onto the next level which
was part of the TfL proposition to government. Looks like that battle
has been lost - at least for now.

The other disappointment concerns the relegation of tram based solutions
but I imagine this reflects the now quite strong "anti" bias in
government and the understandable decision to pursue LU schemes while
they have the chance as they will deliver more benefit overall.


* Tube air-cooled trains project, which has been mentioned before but
for which I don't have any details (would anyone be able to point me at
any?)


there was an option in the SSL PPP Contract for air conditioned trains
on the SSL network. That option has been exercised. The balance of the
"air cooled" work relates to trials with additional water pipes to cool
deep tube tunnels - as suggested via the LU / Mayor "gives us your
bright ideas" initiative. No idea what lines it will be trialled on.

Found the relevant info online after a little digging - South Bank Uni
are working with LU to introduce a trial at Victoria's Victoria line
platforms where 200 l/s water from the River Tyburn (apparently) is
pumped through a space between the two platforms, and fans draw hot air
from the platforms across the cold water, with an air temperature
reduction of about 5°C. The warmed water will be sent off to the Thames
(presumably by the time it gets there, it will have cooled down).
