China News Service, Chengdu, January 7 (Reporter Liu Zhongjun) On January 7, the nation's first new-generation urban A-type train with a speed of 160 kilometers per hour based on 5G vehicle-to-vehicle communication was officially rolled off the assembly line in Chengdu, Sichuan.
At the same time, the first domestic 2025 intelligent fully automatic driving test platform was officially unveiled.
This indicates that the "Made in Sichuan" rail transit has entered a new era of city-urban rail "interconnection" and smart urban rail technology leading the development.

It is understood that the new-generation fully automatic urban A-type train that rolled off the assembly line this time was jointly developed by CRRC Sifang Co., Ltd., Chengdu Rail Transit Group, and CRRC Chengdu. It is the highest-speed urban A-type train in the country. For the first time in China, fully automatic driving of 5G vehicle-to-vehicle communication at a speed of 160 kilometers per hour has been achieved, which has improved the urban train pedigree, filled the gap in the industry, and realized the first landing of advanced rail transit equipment in the southwest region.

Wang Chenglong, chairman of CRRC Chengdu Locomotive and Rolling Stock Co., Ltd. (hereinafter referred to as CRRC Chengdu), said that the new generation of municipal A-type trains has a speed of 160 kilometers per hour, which is the fastest urban A-type train in China. It can be interconnected with the subway to realize the "city center". "To the city center" is a direct station, perfecting the city railway train pedigree.
The train adopts advanced technologies such as 5G vehicle-to-vehicle communication, fully automatic driving, and intelligent operation and maintenance. It represents the advanced level of "comprehensive, green, safe, and intelligent" in the industry. It is the cutting-edge scientific research achievement of intelligent technology and equipment in the demonstration of intelligent urban rail construction.

Walking into the train compartment is more spacious than ordinary rail trains and the environment is comfortable.
"The train adopts 5G communication technology to realize signal transmission between vehicles and realize automatic unmanned driving of vehicles. 5G technology has faster transmission speed, greater transmission flow, reduced ground equipment investment, and lower operating costs." CRRC Chengdu Southwest R&D Wan Li, director of the Central Product Engineering Department, said that the carriage has two windows that are different from the others. One can be used to click on the Internet, and the other can adjust the brightness.
In addition, the train is safer, the collision performance has been improved from 25 km/h to 36 km/h, and the use of information security with separation of internal and external networks, active obstacle detection and fire protection design to meet EN45545 are the first in China to build a speed of 160 kilometers per hour. A comprehensive constitutive safety system for type A vehicles in the city.
At the same time, the 2025 intelligent fully automatic driving test platform settled in CRRC Chengdu was also officially unveiled. The platform is a comprehensive platform integrating collaborative innovation, domestic advanced, open integration, and value added.
Created by CRRC, Chengdu Rail Transit Group, Southwest Jiaotong University, etc., it integrates 5G, big data, AI, industrial Internet and other technologies. It is the first integrated rail transit equipment intelligent test base based on real cars in China.
At the same time, the platform can provide test verification and testing services for fully automated driving technology, trains and equipment.
