Shanghai is hot recently (good news is, it will cool down very soon). Thanks to the good air-con in both metro stations and metro carts, it is very good experience as long as you stay inside the Metro System, but not several carts.
The air-con systems on several train carts don’t work very well. They just produce very weak cold air, so the cart is very hot. I got onto such a train today.
Before they are able to fix the air-con problem, the Metro company put a big blue box in the middle of the cart and put big block of ICE in it. The ice really worked. The cart is not hotter than other places.

I Appreciate It
After running a company for a while, I understand even the richest company has limited resources. To workaround the constraints and get a reasonable result is the responsibility of the management team. I know in ideal world, air-con does not break, and if it does breaks, people can fix it immediately. Even if it cannot be fixed, there are spare carts to put into operation. However, the real world may not be that way.
So they found innovative way (although people may think it stupid ) to solve the problem with the resource they have. I believe this is a much better approach than the approach of the City Terminal Station. I love programs with small money but made big impact.
