RailCrawler - Track Inspection Vehicle

Abstract: Railways are widely used for transportation for passengers as well as goods. But safety remains a major concern due to problems like cracks in railway tracks and obstacles present on the track. If problem like this are not detected early, they can lead to serious and large accidents. Traditional inspection methods mostly depend on manual checking, which is time taking and may not always detect small faults or obstacles. For this problem, our project presents RailCrawler , a smart railway track inspection system. Our system uses sensors to continuously monitor the condition of railway tracks while moving on them. It is capable of detecting both cracks in the track and obstacles such as stones or other objects placed on the railway path. When an abnormal condition is found, the system immediately sends an alert message along with location details to the concerned authority. Also provides quick response by activating safety features like stopping the system and providing a warning signal. Our system reduces manual effort and helps in faster detection. It is simple, low cost, and easy to implement. Overall, it provides a practical solution to improve railway safety and reduce the chances of accidents.
