What must be considered in addition to static geometry when measuring track compliance?

Dynamic deflection under train movement

When measuring track compliance, it is essential to account for dynamic deflection under train movement. Static geometry alone refers to the fixed dimensions and positioning of the track, but trains do not operate in a static environment. As trains move, they exert forces on the track that can cause deflections and changes in geometry due to factors such as speed, weight, and the dynamic interaction between the train wheels and the track structure. This dynamic behavior needs to be assessed to determine how well the track can maintain its structural integrity and operational safety during actual service conditions. Taking into account these dynamic deflections allows for a more accurate assessment of track performance and compliance with safety standards.
