The Tianjin–Pukow Railway Operation (early August to mid November, 1937) was a follow up operation to the Battle of Beijing-Tianjin of the Japanese army in North China at the beginning of the Second Sino-Japanese War, fought concurrently with the Beijing–Hankou Railway Operation. The Tientsin–Pukow Railway Operation was not authorized by Imperial General Headquarters. The Japanese advanced following the line of the Tianjin-Pukou Railway aiming to the Yangtze River without meeting much resistance. The Japanese advance stopped at Jinan on Yellow River after majority of the participating Japanese forces were redirected for the Battle of Taiyuan and replaced by parts of the newly formed 109th division.
