Why is the Victoria line so hot these days?
 

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?

Victoria line is completely underground - it does not have a natural
source of fresh air, like most other lines.

Perhaps its because Victoria-line trains remain entirely underground
while in service.

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.

The CCO (Coasting Control Override) trial might have some effect.

Always has been hotter (well as long as i've been travelling on it).

I've asked this before on here, the answer i got was that it's to do
with the fact that the Vic line is completely underground and so the
trains don't have any fresh air to cool off in except when they go to
the depot.

It's really noticable at Highbury & Islington where the FCC platforms
are like a fridge in comparison

You completely underground ( with a tunnel to the surface depot at
Northumberland park).

I'm not convinced its because its completely underground. After all
the northern line is underground all the way from mordon to east
finchley and golders green. Quite long enough for the tunnels to build
up huge amounts of heat but its not as hot as the victoria line ,
which does have the surface exit to the depot near seven sisters
anyway.
