Abstract： Over the past two decades，China’s high-speed trains have advanced froma follower toa global leader，achieving the highestcommercial operation speed，deploying the largest fleetofhigh-speed trains，recording the fewest failures per 100km ，and delivering the best running stability worldwide. High-speed trains have not only become aprominent symbol of nationaldevelopment，but alsoa vivid representationofequitable acess to the benefits of modernization in the new era.The keyto this remarkable successlies in the exceptional system integrity achieved in China’s high-speed trains.System integrity includes structural integrity，dynamic integrity， and functional integrity.This article defines the concept of system integrityand provides acomprehensive interpretation. Intelligent operation and maintenance of high-speed trains has emerged as a major research focus in recent years. Aiming to safeguard system integrity， this article explores inteligent operation and maintenance strategies，including dynamic condition monitoring and evaluation，inteligent service life prediction，and preventive maintenance planning.
