“…Several studies have reported the feasibility of the fiber-guided LST in the applications for the inspection of coating thickness and laminates dis-bond using laser spot, line scanning thermography and LAST. These studies prove that fiber-guided heating is a valuable and safe system towards advance LT inspection [21]. However, most LST studies use the fiber-guided as a stationary heat source.…”

“…However, monitoring the condition of the sub-ballast is challenging, as the substructure remains hidden from view unless the main ballast is evacuated [22]. Non-destructive testing methods, such as visual testing, automatic visual testing, ultrasonic testing, and radiographic testing [23,24], have been used to monitor the condition of the sub-ballast structure. However, these methods require heavy equipment and incur high costs, which disrupts and delays traffic operations [22].…”

“…In 2023 alone, numerous articles have been published on the subject of NDT. For example, Mićić et al [ 2 ] reviewed a wide range of NDT methods for identifying and classifying rolling contact fatigue (RCF) rail defects, mostly squat and head checking (HC) defects. Ramírez et al [ 3 ] compiled a comprehensive state-of-the-art review on NDT techniques applied to additive manufacturing.…”
