Abstract: In European Train Control System, when a train runs across regions or countries, the train may not adapt to the loading gauge, traction system and axle load category supported by the railway line ahead, and the on-board equipment is required to monitor the route suitability. The trackside equipment provides to the on-board equipment with route suitability data ahead of the train. The on-board equipment monitors whether the train adapts to the line ahead and carries out safety protection to ensure the safety of train operation. This paper introduces the basic concept of route suitability, and expounds the basic principle and common scenario of on-board equipment monitoring route suitability data.

Key words: European Train Control System, on-board equipment, route suitability

摘要： 在ETCS列控系统中，列车跨区域或跨国家运行时，列车可能与前方线路支持的装载限界、牵引系统、轴重类别不适应，需要车载设备对进路适应性进行监控。地面设备向车载设备提供列车前方的进路适应性数据，车载设备监控列车是否适应前方的线路，并进行安全防护，保证列车运行安全。介绍进路适应性的基本概念，阐述车载设备监控进路适应性数据的基本原理和常见场景。
