Riders in north to stay warm on new trains

A cold-weather subway train runs a test in Harbin on Aug 21, 2012. China's first such trains, produced in Changchun, Jilin province, will start running in Harbin later this month. The trains are designed with special heating and heat preservation. For example, they have high-power air conditioners and electric heaters under the seats, to keep them running in extreme cold weather, such as -38 C. [Photo/Xinhua]
