What is a method used to check the creeping of rails?

The method used to check the creeping of rails involves employing anchors. Rail creep refers to the longitudinal movement of rail on its sleepers or ties, which can occur due to temperature changes, train loads, and other factors. To mitigate this creep and maintain the alignment of the tracks, anchors are installed. These anchors hold the rail in place and prevent it from moving longitudinally.

By securing the rail, anchors help maintain the gauge and alignment of the track, which is crucial for safe and efficient train operations. The effective use of anchors ensures that the rails remain in the correct position relative to one another and reduce the risks associated with rail movement over time.

Ballasts serve an important function in stabilizing the track structure, but they do not directly prevent rail creep. Rail clamps are used to secure the rail to the ties but, like ballasts, they do not specifically address the issue of longitudinal movement. Support trusses are structural elements that provide support for overhead structures but are not relevant to the management of rail creep.
