I've noticed the victoria line seems to be much warmer than the other
lines these days (or maybe it always has been but I've not noticed).
Is this because the trains are more frequent , or they use up more
energy on ATO , or the tunnel ventilation isn't so good , or is there
some other reason?

Of the deep tube lines, the Central, Northern and Jubilee are cooler as they
use more modern traction and braking technology that doesn't create so much
heat. The Vic should be cooler when it gets new trains in 2009.
