In 1945, the Soviet Union invaded and overran Manchukuo. Rolling stock and movable equipment was looted and taken back to the Soviet Union; some was returned when the Chinese Communist government came into power. "Mantetsu" itself was dissolved by order of the American occupation authorities in occupied Japan. The People's Republic of China government later merged the northern half of the South Manchuria Railway's mainline (the Renkyō Line) with other railway lines to form the present Beijing–Harbin railway.
