Regarding the heat generated from braking. I was surprised to find out that in our (very small) subway system the stations are higher than the rest of the track. This slows down the train as it is approaching the station and helps it regain speed when it leaves the station. A quite obvious idea, but must admit I might have not thought about it.
In some cities they are building district cooling [1] (comparable to district heating). Might be quite a difficult solution in densely built areas of course.

- rzzzt 8y agoCan passengers feel a mild roller coaster effect, or is the incline too small for that?
- Gravityloss 8y agoI would assume the incline would be impossible without seeing the horizon, because the car also accelerates. I guess you mean the increased gravity feeling at the bottom of the track?
- rzzzt 8y agoRight. I traveled once on a long-distance bus line that acted like a zero-gravity plane for a split second, as it went over a bump in the road. Just wondering if the experience would be comparable :)
- mislankanova 8y agoThe Central Line in London has some of its stations designed in this way, and you can certainly feel the slope when the train enters or leaves the station. After riding the Central Line frequently for one year I got used to that feeling and start to think that there is something missing when I ride other lines...
- sdx23 8y agoSo there is no (electric) brake energy recorvery? I find this surprising; especially for newer carts I'd presume that'd be default.
