On Metro, they're riding in the cold

WHILE the mercury continues to climb outside, passengers are actually shivering inside some very well air-conditioned subway trains.

Pictures uploaded by passengers online showed one passenger seated on the Metro Line 9 covered with a blanket to keep warm. Similar scenes were observed along the newly opened Metro Line 10.

Metro operators said yesterday that they had raised the temperature one degree Celsius to about 25 degrees in trains on Line 9.

Ma Wen, an engineer who works on the Metro air-conditioning system, said various factors can affect how passengers feel on a train.

Frequent opening and closing of doors, for example, brings exchanges of hot air with the cool, said Ma.

"We shall hear majority's opinions on cold or hot instead of individual complaints," said the engineer.

Trains are undergoing a renovation that allows passengers to speak to the driver through the emergency intercom system and ask for the air-conditioning to be adjusted.
