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?
