Abstract: Provided are a system and method for diagnosing operational safety of railcars in which one or more vibration sensors installed in each car of a train measure and analyze vibrations generated from the running car, running information including the travel location and travel speed of the car is added to vibration data and transmitted to a central control system, integrated running information is analyzed through pretrained artificial intelligence (AI) to estimate an abnormal part of the cars or railroad, and the AI is retrained through big data analysis.
