As mentioned upthread, for reasons of tight space and twisty track,
I think it highly unlikely that any LU tube stock will have

narrow and low the doorways would have to be!

"Since Metronet's collapse London Underground claims to have
saved £2.5bn through the renegotiation of contracts, revising
the upgrade programme, better procurement and operational
efficiencies. This new work will be complemented by a fleet of
191 new air-conditioned walk through trains. It will mean
passengers will experience a more reliable service, with 50%
greater capacity."

Or are those SSL?


Bound to be. There's no plans to air-condition anything tube-sized
either, is there?

There was talk of a proposed experiment on the 1973 Picc trains, but
I've not heard anything of it lately. The idea was to freeze ice in the
above-ground parts of the line, which would then be used to cool the
trains in the tunnels. I wonder where they'd have fitted it all in?
