What are the main components of Dalian track components?

Dalian track components are the general designation of the parts, components and some materials that make up the track structure. The track bed, sleeper and steel rail are the main components of the track structure, while the joint clamp, iron pad, studs, fasteners, various bolts and nuts, anti climbing equipment, gauge bar, turnout and crossing, derailer, bumper, rail expansion joint and other parts are collectively referred to as the line materials. Although their types and materials are different, the Dalian track structure used to form it has good overall strength and stability.

  

Moreover, the improvement of the performance of any part of the track structure can improve the overall performance. However, it must be considered comprehensively according to the system principle. For example, when concrete sleepers replace wooden sleepers, the rail fastenings and track beds should be changed accordingly; When laying jointless track, there are new requirements for rail joints, fasteners and track bed; When paving a new type of foundation under the rail, the elastic property of the rubber pad under the rail and the stability of the subgrade bed shall be improved at the same time.
