[LETTERS TO THE EDITOR]Subway cars feel like refrigeratorsI ride the Seoul subways, and usually get on the first car on the train. That makes it easy to ask the engineer, as I often have to do, to turn down the air conditioning. The summer heat is already gone, but the trains usually have their air conditioners going full-blast.
Of course air conditioning should be turned up when trains are full of riders during the rush hour and inside temperatures rise. Still, I do not understand why air conditioning is still on late at night when few people are using the subway. The subway corporation always complains about its deficits. Here’s a way to save some money.
Also, I think it is a problem that passengers have a hard time communicating with engineers. It is inconvenient for passengers to have to knock on the engine compartment door in order to talk to them.
