The Tube has a real ventilation issue - not just the brake dust, but also temps and staleness. Some of those lines, it’s like a 24/7 sauna!

- walthamstow 1y agoI think I read that the warmth from people and braking has baked some of the clay earth around the tunnels, making them even more insulative!
- azath92 1y agoBecause of how old they are there is some really interesting long term data as the earth itself around the tunnels reaches a new thermal equilibrium. In looking for a source, i found a good wikipedia article on tube temp in general. These comments and the article made me see how much of it is/was due to braking.
