Railways are large infrastructures and are the prime mode of transportation in many countries.The railways have become a prime means of transportation owing to their capacity, speed, and reliability.Even a small improvement in performance of railways has significant economic benefits to rail industry.Thus, a proper maintenance strategy is required to govern optimization of inspection frequency and/or improvement in skill and efficiency.Accidents happening due to track breaking have been a big problem for railways for life security and timely management of services.This breakage needs to be identified in real time before a train actually comes near to the broken track and get subjected to an accident.In this paper, different kinds of rail defects inspection and maintenance methods are described and a basic algorithm is readdressed that makes use of wireless acoustic sensors for detecting cracks and breakages in the railway tracks.
