A high-speed train service will start operation on Monday, linking some of the most northernmost cities in China.
The rail line will link Harbin, the capital of northeast Heilongjiang, with Qiqihaer, Heilongjiang's second largest city. It will cut the travelling time between the two cities from 3 hours to some 85 minutes.
The service will have 28 trains designed to endure severe cold - up to minus 40 degrees Celsius, as some critical parts of the 5A train are replaced with cold-resistant stuffs.
Average temperatures for Qiqihaer and Harbin in January are minus 19.2 degrees Celsius and minus 18.3 degrees Celsius, respectively.
