(ECNS) -- Two more metro lines in Beijing are offering varied temperatures inside their train cars amid efforts to improve commuter experience during summer.
Subway Line 2, the inner rectangular loop line, and Line 13, which arcs across suburbs north of the city, have joined Line 6 in allowing passengers to choose cars with either "strong-air-conditioning" or cars with "light-air-conditioning."
After technical upgrades to the train cars, temperatures will be automatically set at 26 or 24 degrees centigrade for Line 2 and 26 or 23 degrees centigrade for Line 13, according to the subway operator.
Passengers can easily find information at subway stations before boarding regarding the temperature differences inside train cars, with blue representing a car with a colder temperature and green, a little warmer.
