    Dr. Hannah Fry made a short video about this recently – this kind of heat retention is why London Underground stations are so bloody hot, because the clay tiles lining the underground tunnels have absorbed heat from trains braking day in and day out and are constantly releasing excess heat into the air at the stations

      Interesting. So adding regenerative breaking to the trains would actually reduce the heat.
