Health trackers for rail tracks and other structures

Structural health monitoring records the current "state of health" of structures and infrastructure. This allows "illnesses" to be diagnosed at an early stage and treated. Like people, structures and infrastructure age. To prevent serious illnesses such as a heart attack, we humans, for example, can undergo health screening at regular intervals. Or these days, carry small, digital health trackers which continually measure our bodily functions, such as pulse, and inform us about overly high values. And for structures, roads and railways there is also "health screening" - routine inspections at preordained maintenance intervals, and "health trackers" - sensor systems installed on structures which automatically and continually relay diagnostic data. " 'Health tracking' on structural components continuously supplies key data, thus providing information about the smallest cracks and deformations in structures and recognising possible weaknesses.
