--- Modified the requirements of the crossing signal (see 5.11, 5.12, 1989 version 4.4.1, 4.14.2);

--- Removed the white light display, increased power or equipment failure information (see 5.13, 1989 version 4.4.2);

--- Revised the requirements of the audio (see 5.14, 5.15, 4.4.3, 4.14.3 of the 1989 edition);

--- Modified the requirements for the crossing signal of the crossing (see 5.17, 5.18, 5.19, 5.20, 4.11 of the 1989 edition);

--- Deleted the section of the busy road crossing, in order to improve road driving efficiency, it is advisable to use automatic with speed alarm Signal" (see 4.13 of the 1989 edition);

---Modified the requirements of automatic column wood (see 5.21, 5.22, 5.23, 4.15 of the 1989 edition);

---Modified the setting principle of the control panel and the dial of the crossing (see 5.24, 5.25, 5.26, 5.27, 4.16, 4.17 of the 1989 edition, 4.18);

--- Increased the requirements of the crossing machinery room (see 5.28);

--- Revised the requirements for monitoring equipment (see 5.29, 4.8 of the 1989 edition);

--- Increased the requirements for dustproof and waterproof outdoor equipment (see 5.30);

--- Increased reliability, availability, maintainability and safety requirements (see 5.33);

--- Increased requirements for control and protection system software (see 5.34);

--- Increased requirements for safety related electronic systems for signals (see 5.35);

--- Increased electromagnetic compatibility performance requirements (see 5.36);

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