Rail Shoulder design standard

Design speed: Railway lines with different design speeds have different requirements for Rail Shoulder. High-speed Rail generally requires Rail Shoulder for greater stability and durability.
Load requirements: According to the factors such as axle weight, running speed and running density of the train, the load required by the Rail Shoulder is determined, so as to determine its design strength.
Environmental conditions: climate, geological conditions, etc., will also have an impact on the design of Rail Shoulder. For example, in cold areas, the frost resistance of materials needs to be considered, and in areas with complex geological conditions, problems such as foundation treatment need to be considered.

Non-slip: The connection between the Rail Shoulder and the rail needs to ensure sufficient friction to prevent the train from slipping during high-speed operation.
Durability: Considering the long-term operational needs of the Rail system, Rail Shoulder needs to be durable enough to withstand long-term loads and harsh environments.
Earthquake resistance: In areas where natural disasters such as earthquakes occur frequently, the seismic performance of the Rail Shoulder also needs to be considered.

Size and shape: The size and shape of the Rail Shoulder need to be determined according to the specifications of the rail, the gauge and the arrangement of the sleeper and other factors.
Material selection: The selection of materials needs to consider its strength, toughness, wear resistance, corrosion resistance and economic factors. Commonly used materials include cast iron, ductile iron and so on.
Installation and fixing: The installation and fixing method of the Rail Shoulder needs to ensure that the connection between it and the rail and the sleeper is firm and reliable to ensure the stability of the track structure.
