IEC 62427:2024描述了证明机车车辆(RST)和列车检测系统(TDS)之间兼容性的过程。它描述了列车检测系统、机车车辆和牵引供电系统的特征。 值得注意的是，本文件中没有详细说明机车车辆和基础设施在物理尺寸方面的技术兼容性。 本文件一般不适用于在本文件公布之前被接受为兼容的机车车辆、牵引电源和列车检测系统的组合。然而，在合理可行的情况下，本文件可应用于可能影响兼容性的机车车辆、牵引电源或列车检测系统的修改。在没有建立兼容性规则和过程的情况下，可以使用详细过程。 这第二版取消并取代了2007年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)通用兼容性过程，根据是否存在已建立的兼容性极限，将其分为两阶段过程； b)列车检测系统表征规则； c)机车车辆表征规则； d)用于表征电力系统的规则； e)在已建立的CENELEC兼容性标准的注释中提供了信息性参考； f)更新术语。

IEC 62427:2024 describes a process to demonstrate compatibility between rolling stock (RST) and train detection systems (TDS). It describes the characterization of train detection systems, rolling stock and traction power supply systems.
It is worth noting that the demonstration of technical compatibility between the rolling stock and infrastructure with respect to physical dimensions is not detailed in this document.
This document is not generally applicable to those combinations of rolling stock, traction power supply and train detection system which were accepted as compatible prior to the publication of this document. However, as far as is reasonably practicable, this document can be applied to modifications of rolling stock, traction power supply or train detection systems which can affect compatibility. The detailed process can be used where no rules and processes for compatibility are established.
This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) generic compatibility process, which is broken into a two-stage process depending on whether there are established compatibility limits or not;
b) rules for characterization of train detection systems;
c) rules for characterization of rolling stock;
d) rules for characterization of the power system;
e) informative references are provided in notes to established CENELEC standards for compatibility;
f) terminology is updated.
