Fujiang river in Mianyang, Southwest China's Sichuan Province, has suffered its worst floods in 50 years.
The floods threatened the Fujiang bridge, a crossing for trains between Baoji, Shaanxi Province and Chengdu, Sichuan.
To stabilize the bridge and prevent it from collapsing, a cargo train, weighing 8,100 tons, was placed on the bridge.
It's the second time such a method was used to help the bridge get through the floods.
