Among the problems with aircon on the tube lines is - where do you dump the
heat? Presumably on, say, the Central or Piccadilly lines it would be
possible to devise a system whereby the heat was retained on the train
until it got to the open air, and then dumped, but Victoria Line trains
stay underground all the time they are in service. No use cooling the
trains if you just heat the tunnels even more.

AIUI, however, the new rolling stock is going to have some sort of new
venting system that will make journeys cooler.

Right?

Right. it's basically just much better ventilation. Someone posted a study
by some physicists a while back that suggested it would make the insides
of the cars a few degrees cooler. Not an awful lot, but significant.
