CHANGCHUN - A Chinese company built a cold-resistant subway train on Tuesday, expecting to put the train into operation in northeast China's city of Harbin by the end of the year, the company said.

The train, which features cold-resistant materials and inert gases in its design, can operate in temperatures as low as minus 38 degrees Celsius, according to a subsidiary of China CNR Corporation Limited, one of the country's two major train manufacturing companies.

The train is also the lightest aluminum subway train ever produced in China, the company said.

The train will be used in Harbin, provincial capital of Heilongjiang province, by the end of 2012, the company said.
