With temperatures below freezing and snow falling the length of the route, China's first high-speed rail line that runs a long distance through regions with extremely low temperatures started service on Saturday.
The 921-kilometer line links Harbin, capital of China's northernmost province of Heilongjiang, and the port city of Dalian in Liaoning province. The high-tech train, designed to withstand temperatures ranging from minus 40 up to 40 C, marks a new milestone in the country's effort to build the largest high-speed railway network in the world.
