Concrete surface in contact with direct noon sunlight is always gonna be scorching hot, 50°C is not far fetched. On a super hot day you can cook an egg on concrete. These surface also tend to heat up slow but also lose heat slowly, which is why even after a couple of hour after sun down it will still feel warm to the touch, creating what is known as urban heat trap.

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.
