The Yakeshi-Linhai Railway, operated by CR-Harbin, connects Yakeshi in Inner Mongolia with Mangui Railway Station, the terminus of the regional network. Running through a permafrost zone with over 210 frozen days each year, the line serves as a "lifeline" for residents in the forest areas. As late autumn sets in, the region is painted in rich colors, attracting visitors eager to experience the northernmost scenery of China.
