No matter what form of rail transit, there is a common characteristic, that is, have to rely on the train line transfer switch, can not be changed by the driver. The exception is one ton tub models, some old-fashioned tram to the terminal, the driver jumped out of the car to get by in person Stubbs turnout. U-turn to go to the fork line. Individual forest railway, mining railway is off by throwing a switch drivers themselves. At this point, the driver, who is also member of the post switchman. But this backward approach can not be used on a busy railway and subway, high-speed railway and other modern rail transportation including basic rail switching points, sharp rails and mechanical switching points. When locomotives from A into B shares Road Track, manipulate mechanical derailleur so sharp track mobile location, a snug basic tip rail track 1 track 2 tip from basic track 2, which had opened the B shares Road, A shares closed the road, rolling stock into the connecting part of transition curve along the guide rail to the frog and guard rail unit. This unit includes a fixed frog heart, wing rail and guard rail, the role is to protect the safe passage of the wheels of the two strands of the cross rail lines. The basic track is made of a 12.5m or 25m standard common rail section, the main share of the straight line a ton tub purchasing shares by the derailleur side gauge of each part in the factory prior to a predetermined bend or fold adoption curve type. Typically, the turnout in the rail cant no one ton tub manufacturers, in order to improve rail force conditions, the basic speed rail has a 1:40 turnout rail cant. In addition to the basic rail wheels to withstand vertical pressure, but also with the tip of the lateral horizontal force to bear rail wheels. In order to prevent lateral movement of the basic tracks a ton tub, set in its outer side rail support. In order to increase the rail surface hardness, improved wear resistance and keep the tip of tight state rail good, basic rail head surface is generally also quenching. A ton tub models, a ton tub, Xin Yang Machinery by Lin Xin Yang Machinery Industry Co., Ltd. Taizhou. Forest City Xin Yang Machinery Industry Co., Ltd.
