The first IEC international standard in the field of rail traffic signal technology hosted by our country has been officially released and implemented.

Recently, the International Electrotechnical Commission released the "Urban Rail Transit Non-UGTMS Urban Rail Transit Signaling and Control System". This is the first international standard in the field of IEC rail transit signaling technology organized by the National Railway Administration and led by China, marking a new breakthrough in the internationalization of China's rail transit standards. The newly released international standard "Urban Rail Transit Non-UGTMS Urban Rail Transit Signaling and Control System" is an important component of the rail transit signaling control system standard, specifying the functional requirements of signals and control systems in rail transit that rely on visual or non-continuous train control supervision, applicable to all GOA0 and GOA1a automation levels of rail transit systems, laying a technical foundation for the interoperability, interchangeability, and compatibility of system devices.
