本文件规定了城市轨道信号和控制系统的最低功能要求:•在视线范围内运行或使用具有间歇性列车控制的自动联锁信号，•现有UGTMS标准EN 62290系列未涵盖，•不构成城市交通控制系统的一部分，但可能与此类系统连接。 该文件仅限于最低功能要求，允许用户定义更具体的功能要求 基于顶层系统需求给定框架的需求。这份文件不是 适用于采用连续数据传输和连续数据传输的城市轨道交通指挥控制系统 通过列车保护配置文件对列车运行进行监督（EN 62290系列已经涵盖）。 交叉引用:IEC 60050-821:2017IEC 62290EN 12675EN 62290CEN/CLC指南26购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies minimum functional requirements for urban rail signalling and control systems:• which operate on line of sight or using automatic interlock signalling with intermittent train control,• not covered by the existing UGTMS standard EN 62290 series,• not forming a part of an urban traffic control system but possibly interfaced with such systems. The document is restricted to minimum functional requirements which allow users to define more specific requirements based on the given framework of the system requirements at top level. This document is not applicable to command and control systems for urban rail using continuous data transmission and continuous supervision of train movements by train protection profile (already covered by the EN 62290 series).Cross References:IEC 60050-821:2017IEC 62290EN 12675EN 62290CEN/CLC Guide 26All current amendments available at time of purchase are included with the purchase of this document.
