Harbin–Manzhouli Railway or Binzhou Railway (simplified Chinese: 滨洲铁路; traditional Chinese: 濱洲鐵路; pinyin: bīnzhōu tiělù), is a double-track electrified arterial railroad in Northeast China between Harbin and Manzhouli on the Russian border. The line was originally built by Russia as the western branch of the Chinese Eastern Railway. Today, the 934.8 km (581 mi) Binzhou Railway remains a major rail transport corridor across Northeast China, traversing Inner Mongolia and Heilongjiang Province. Major cities and towns along route include Manzhouli, Jalainur, Hailar, Dayan, Yakeshi and Zhalantun in Inner Mongolia, and Qiqihar, Daqing, Anda, Zhaodong and Harbin in Heilongjiang.
The Binzhou Railway begins in the west at Manzhouli's border crossing to Russia and runs eastward across the Hulunbuir grasslands, through the forests of the Greater Khingan range, the oilfields of Daqing and rich farmland of the Songhua River valley to Harbin.
