en.Wedoany.com Reported - Chengdu, Sichuan Province, China recently disclosed development data for its rail transit industry. The city has formed an industrial scale of nearly 200 billion yuan, gathering over 310 above-designated-size rail transit enterprises, cultivating 7 chain leader enterprises and 39 specialized and sophisticated "Little Giant" enterprises, and assembling high-end talent including 5 academicians of the Chinese Academy of Sciences and Chinese Academy of Engineering. The whole vehicle production capacity has exceeded 1,500 units. Chengdu's rail transit network mileage has reached 758 kilometers, with an average daily passenger flow exceeding 6.4 million trips.
In early 2026, Chengdu Rail Group and Casco Signal Ltd. launched Chengdu's first "Rail + Low-Altitude" dual headquarters project, exploring low-altitude technology applications in rail transit scenarios. Wang Lei, head of the Industry Investment Group under Chengdu Rail Group, introduced that subway construction involves more than 30 specialties including survey and design, civil construction, electromechanical installation, and vehicle equipment. Chengdu's rail transit construction intensity once ranked first in China for five consecutive years, with 400 shield machines tunneling underground simultaneously during peak periods.
In terms of vehicle manufacturing, the first "Made in Chengdu" train rolled off the production line at CRRC Chengdu Co., Ltd.'s Xindu factory in 2016. Over 70 upstream and downstream enterprises subsequently gathered in Chengdu, providing complete system support for whole vehicles including traction, braking, air conditioning, and doors. Regarding signaling systems, in 2021, Traffic Control Technology Co., Ltd. established its second national headquarters in Chengdu's Jinniu District. The fully automatic operation system independently developed by Chengdu TCT has been applied to Chengdu Metro Lines 13, 27, and 30. The local supporting rate for Chengdu Metro Line 13, China's first urban fully automatic operation train with a speed of 140 km/h, reached 71.63%.
Zhang Haibo, National Engineering Survey and Design Master and Deputy Chief Engineer of China Railway Eryuan Engineering Group Co., Ltd., recalled that during the construction of Chengdu Metro Line 1, an expert team from Southwest Jiaotong University solved the shield tunneling challenges in water-rich sandy cobble geology. CREEC undertook the line design and feasibility study, China Railway No. 2 Engineering Group Co., Ltd. completed the construction, and leading enterprises such as CRRC and China Railway Group subsequently expanded the rail transit industry cluster.
Huang Chao, General Manager of Chengdu TCT Rail Technology Co., Ltd., stated: "Chengdu is not just a market; it is a fulcrum to leverage the western region, radiate across the nation, and face the world." The "Chengdu-developed" rail transit inspection system has been implemented in Chongqing and Xiamen, and signaling system-related technologies have been adopted in cities such as Taiyuan, Shenzhen, Beijing, Wuhan, Nanning, and Hong Kong.
