Railway marshalling station is used to decompose and group freight trains. It is named because its longitudinal section looks like the hump back of a camel. The line plane and longitudinal section of hump are composed of four parts: peak pushing part, peak platform, peak sliding part and parking lot.
Hump is the main feature of marshalling station, and it is an important equipment for rapid assembly and disassembly of freight cars. The so-called hump is a kind of shunting equipment, which is built on the ground like a camel's hump, designed with a proper slope and laid with the railway. It uses the potential energy generated by vehicle gravity and hump gradient, supplemented by locomotive thrust, to disassemble the train. This is the main method of disassembling cars in marshalling station.
