---Modified the requirements of automatic column wood (see 5.24, 5.25, 5.26, 4.17 of the 1989 edition);

---Modified the setting principle of the control panel and the dial of the crossing (see 5.27, 5.28, 5.29, 5.30, 4.18, 4.19 of the 1989 edition, 4.20);

--- Increased the requirements for the machinery room of the crossing (see 5.31);

--- Revised the requirements for monitoring equipment (see 5.32, 4.8 of the 1989 edition);

--- Increased dust and water resistance requirements for outdoor equipment at the crossing (see 5.33);

--- Increased reliability, availability, maintainability and safety requirements (see 5.36);

--- Increased requirements for control and protection system software (see 5.37);

--- Increased requirements for safety related electronic systems for signals (see 5.38);

--- Increased electromagnetic compatibility performance requirements (see 5.39);

--- Revised the train approach notification time and the approximate segment length calculation formula (see Appendix A, Appendix A of the 1989 edition).
