Features: This standard is a national standard and came into effect on August 1, 2003. The mandatory provisions of the original "Design Code for Underground Railways" GB50157-92 and the original "Design Code for Underground Railways" GB50157-92 were simultaneously abolished. This standard is based on the original 13 chapters and has been expanded to 23 chapters with the addition of 4 appendices. The newly added content includes operation organization, A-type vehicle clearance, elevated structures, environmental and equipment monitoring systems, automatic ticketing systems, environmental protection, and more. Many provisions in the original chapters have also been expanded and deepened in line with the times. At the same time, based on expert recommendations and widespread recognition, the name of this standard has now been simplified to "Metro Design Code." This standard applies to the new engineering design of metro systems using steel-wheel and steel-rail systems. The design of metro systems undergoing renovation, expansion, or with a maximum operating speed exceeding 100 km/h, as well as similar urban rail transit projects of other types, may refer to this standard for implementation.
