Abstract
Here we investigate the use of impact-based vibration applied to steel rail structures to observe the effects of axial stress in the structure. Observations from field and laboratory tests using a contactless sensing configuration show that resonances generated by a single impact have different sensitivities to the same stress/temperature change. The study identifies resonances that may characterize absolute stress state of the rail that are minimally affected by complicated rail substructures.
