Question - why is the Central Line so warm?

OK, now I understand many of you guys are not in London, nor are the ones who do likely to use the tube frequently.
However, enough cumulative brainpower/knowledge could be the solution.
So - why is the Central Line so warm, and why is it usually warmer than other lines?
I understood heat generally was generated underground through a) having a lot of people and b) heat coming from the brakes to stop the trains.
However, if that were the case, it wouldn't explain why the central line is so consistently hot, even when it's not busy, and why it so much wamer than other lines, which have a similar amount of people using it and, ostensibly similar train/braking technology.
Any ideas?

Possibly because it's in the middle of the system and does not get the cool air from overground lines entering it?
I don't know, but I've noticed the same thing when I've used the Underground.0 -
It's so deep underground that you are close to magma.0

Closer to the centre of Hell?
None of the above should be taken seriously, and certainly not personally.0 -
It probably is to do with the depth of it and the fact that it gets little fresh air. It underground all the way from White City to god knows where in east London.
Whatever the reason its uncomfortable enough to get me to use my bike instead

Correct me if i'm wrong but doesn't temperature go up 1c per 70 feet descended?Norfolk, who nicked all the hills?

I have no idea but I doubt the depths the tube goes make much difference.0 -
Perhaps they just turn the heating up to make people even more miserable. If thats possible.0

Someone snapped the knob off of the radiator so it's stuck on "roast you alive" setting?0

Northern line is the deepest I think. The lift at Hampstead is 55.2m!
My guess would be:
1. volume of trains - more trains = more braking = more heat
2. volume of people farting and breathing and talking bollox
3. lack of overground stations

air doesn't circulate because of the depth and the volume of the trains constantly displacing the static air system heats it up
the trains moving through the tunnels act like leaky pistons - when they build up pressure, the energy is dissapated as heat"I get paid to make other people suffer on my wheel, how good is that"

Is it because it's the red one! :?0

Is another name for the Central Line not the equator?

I'm partly correct then Wiggle has caused global warming. 0

This is just a lot of hot air.
