I think the Montreal metro faces a lot of these same issues. It works out in the winter where you don't need to actively heat the space. In the summer, it can be unbearable. I'm not sure if the type of rolling stock (rubber tires + tunnel track) has a major difference from other typical subway cars.

It really doesn't matter much - any amount of heat going into the underground system that is not able to be dispelled in a year-round cycle will heat the ground eventually. Reducing the heat entering the system slows it down, but at some point you have to cool it again.

  Every amount of heat generated will have an equilibrium average temperature. Reducing input heat will lower this equilibrium temperature.

    But that equilibrium could be a lethal temperature.

I personally don't find Toronto or Montreal subways unbearable (warm, but not crazy), while my time in the London Underground was absolutely miserable - I'm not sure how locals handle that kind of stifling heat. Actually, there was one time I was in the old Toronto Osgoode (pre-opera house) station with a -30 degree wind blowing through - that was chilly! Actually, I'm kind of sad that Montreal has so few cars left that play "Fanfare" [0] [0] https://web.archive.org/web/20090823173621/http://observatory.designobserver.com/entry.html?entry=7487 https://web.archive.org/web/20090823173621/http://observator...

  I think the car temps and the station temps are quite different. And maybe it varies by line or car-type in the same system? I've definitely experienced insanely hot cars in Montreal's metro and it previously led me down the rabbit hole to learn why there was no climate control in the system.

  >I personally don't find Toronto or Montreal subways unbearable tbh London is fine too. Problem is if it is the main form of transport then the at-risk members of society use it too. Very old & frail etc.

  The underground gets quite a lot hotter than the legal temperature limit for transporting livestock in the UK. Supposedly the record is 47°C
