What is the primary function of the Surge Res in an air suspension system?

The primary function of the Surge Res in an air suspension system is to compensate for lateral sway on the train. In rail systems, lateral sway can occur during operations due to factors such as track curvature, train speed, and dynamic forces experienced during travel. The Surge Res helps to stabilize the train by absorbing and mitigating these lateral movements, ensuring a smoother ride and reducing wear on both the vehicle and the track.

Maintaining stability is crucial for passenger comfort, performance, and safety, making the role of the Surge Res significant in the overall functionality of the air suspension system. It enhances the train's ability to maintain a consistent path on the track, contributing to safer and more reliable operations.
