Harbin–Qiqihar intercity railway

The Harbin–Qiqihar intercity railway, also known as the Haqi Passenger Dedicated Line, is China's most northerly high-speed railway. It opened for revenue service on 17 August 2015, connecting the two principal cities in Heilongjiang province, Harbin and Qiqihar.

Operating at up to 250 km/h (155 mph), the high-speed trains have cut the fastest journey time between the cities from 3 h to 85 min. Under construction since 2009, the 286 km (178 mi) line has intermediate stations at Harbin North, Zhaodong, Anda, Daqing East, Daqing West and Dorbod (formerly known as Taikang). It is expected to carry around 8 million passengers a year.

The railway is operated with a fleet of 28 CRH5A trainsets which have been modified to cope with the region's severe winter conditions, where temperatures can fall as low as -40°C. Average temperatures for January are reported to be -19.2°C in Qiqihar and -18.3°C in Harbin.
