Because if there is anything Shanghai residents need, it’s more pampering: “…if passengers are unhappy with a train’s temperature, they can speak to the driver through the emergency intercom system. Alternately, they can dial the complaint hotline, 6437000 or advise Metro workers at stations. The air-conditioning temperature setting is based on what is considered comfortable, but passengers may feel cold or hot, depending on how full trains are. Though the temperature has been set when a train leaves the terminal, drivers now can adjust the temperature according to passengers’ needs, said Shentong Group. The new system is on all lines except Line 1, where the air-conditioning system is too old to be upgraded.” [Shanghai Daily] Wow, Shanghai metro, you are opening an entirely unnecessary can of worms. I can only imagine the abuse those emergency intercoms will be seeing in the coming months.
