Drive-by Methodologies Applied to Railway Infrastructure Subsystems: A Literature Review—Part II: Track and Vehicle

Railways are one of the most important means transportation, allowing people and goods to move quickly, environmentally beneficially, efficiently over long distances. To ensure safe reliable operations, regular condition-based assessments trains track paramount importance. Drive-by methodologies, which utilize data collected by onboard monitoring systems as vehicle travels track, have gained popularity an economically viable strategy for extensive networks well vehicles traveling on them. This paper presents a critical review these methodologies applied railway tracks vehicles. It assesses research irregularities, rail conditions, condition supporting elements, highlighting early developments recent papers that provide insights into future practical applications. Additionally, explores works related global evaluation, focusing identification suspension wheelset element damage also discussing challenges towards commercial application. The findings suggest drive-by several promising These include maintenance optimization, proactive fault detection, predictive maintenance, performance health monitoring, data-driven decision-making. By leveraging assessments, operators can optimize efforts, detect faults early, predict remaining component life, evaluate performance, monitor health, make informed decisions based analysis. Finally, comprehensive conclusion summarizes achievements thus far provides perspectives forthcoming developments. applications discussed in this potential revolutionize leading safer more efficient operations days come.
