Detailed Study on Various Techniques for Detecting Railway Track Anomaly

A vital part of today's transportation infrastructure is the railway system that facilitates the massive movement of people and products. With so many people and commodities being transported, the rail tracks could develop defects and flaws over time. The development of these defects might jeopardize the safety and integrity of the rails due to persistent wear and tear, exposure to harsh environmental factors and the enormous loads carried by trains. Hence, to prevent faults and to avoid accidents, it is essential to maintain track safety. Thus, researchers focused on different technologies with different methodologies for detecting the defect that occurred in rail tracks as early as possible. Therefore, this paper summarizes the available methods and technologies for detecting defects and faults in railway tracks.
