CHANGCHUN, Nov. 28 (Xinhua) -- China's high-speed trains that will travel across the country's frigid northeastern regions are designed to withstand sharp changes in temperature, a chief engineer said Wednesday.
The country's first cold-proof high-speed trains are expected to run from Saturday and any problems with sharp changes in temperature that once forced Eurostar to halt services in 2009 look to have been solved.
The trains, to withstand minus 40 degrees Celsius temperature, will travel 921 kilometers between Harbin in Heilongjiang Province and Dalian in Liaoning Province.
CNR Changchun Railway Vehicles Co. Ltd, a subsidiary of the country's major train maker China CNR Corp., developed the cold-proof train cars.
