JR East to monitor Yamanote Line pantographs with AI

East Japan Railway has said it will launch a trial in April of a system that uses artificial intelligence to monitor pantographs on trains running on its busy Yamanote Line in Tokyo to detect defects at an early stage. The railway operator, known as JR East, also plans to use drones to inspect overhead wires and other infrastructure, aiming to reduce the time required to resume operations by 30% when transport service disruptions occur due to equipment problems. Cameras to monitor pantographs, which are located on the roof of a train car and connect the carriage to overheard electrical wires, will be installed near Shimbashi, Ebisu, Mejiro and Uguisudani stations in the capital, the company said Tuesday. The AI system will analyze the images in real time, and if damage is detected, it will notify the control room or other relevant sections. Drones will be dispatched later to inspect overhead wires and other equipment, facilitating faster restoration work.
