Qiqihar was the first provincial capital city to be liberated in the country, and it has made many outstanding contributions to supporting the liberation of the country. The most representative one is the 3005 Hero Train. In 1948, the People's Liberation Army opened the curtain of the Liaoshen Campaign. The Angangxi Locomotive Depot was ordered to transport arms to the front line. They consisted of a special crew of 16 Communist Party members. In the early morning of September 28, 1948, they drove the liberation-type No. 1195 locomotive and hauled 3005 secret arms trains consisting of 32 freight cars. Quietly set off from Angangxi and went straight to Fuxin, the front line of the Liaoshen Battle. On the way, they dealt with enemy aircraft and spies. They escaped bombardment, starvation and freezing, water shortages for locomotives, disguised disguise, and emergency repairs. The locomotives and others were struggling and sent 8 vehicles of ammunition and 22 vehicles of full ammunition to the front line of the liberation of Jinzhou. At the most critical moment during the Liaoshen Campaign, they transported a vehicle of the most critical ammunition for the liberation of Jinzhou and even the Liaoshen Campaign. The victory made an indelible contribution.
