CNR's unit heavy-haul combined train on Datong-Qinhuangdao railway.
I love the view like that a train with green mountains and bridge.
After I reached the top of the Lan Mountain, I could see the trains on LanXin Railroad.
The DF4D was accelerating with loud noise of V16 turbo diesel engine.
The view like that a bridge connect a tunnel is common in Fengsha railway.
