高速综合检测列车的英文缩写为CIT,是一系列应用于中国高速铁路的综合检测动车组列车,是为时速200公里以上高速铁路基础设施定期检测、综合检测和高速检测的重要技术装备,拥有对线路轨道、受电弓接触网、通信信号等基础设施的综合检测能力。高速列车飞驰在铁路线上,车轮撞击轨道的巨大作用力使其发生横向及竖向的变形,为了保持轨道的正常技术状态,必须对轨道产生的位移进行检测,为轨道的正常维 The CIT is a series of comprehensive EMU trains used in China’s high-speed railway. It is an important technical equipment for regular testing, comprehensive testing and high-speed testing of high-speed railway infrastructure above 200 kilometers per hour. Line track, pantograph contact network, communication signals and other infrastructure comprehensive detection capabilities. High-speed train speeding on the railway line, the wheel hit the huge force of the track so that it occurs lateral and vertical deformation, in order to maintain the normal state of the track, the displacement of the track must be detected for the normal orbit of the track
