China’s longest subway loop line features “Jinchuang Intelligent Manufacturing” technology.
2026-11-05
Recently, Phase II of Wuhan Metro Line 12 officially opened for service, seamlessly connecting with Phase I and completing the city’s first metro loop line, which spans 59.9 kilometers. This line is also currently the longest metro loop in China. Among the inaugural trains, a carbon-fiber-themed train drew particular attention, with its comprehensive interior fit-out solution provided by Jinchuang Group.
Lightweighting is a key focus in the upgrade of rail transit equipment. Addressing the need to reduce weight in interior carbody components, Jinchuang Group has developed carbon‑fiber interior parts that integrate functions such as carbody enclosure, equipment protection, and modular decoration. While ensuring full interior functionality, these components reduce material and part usage, helping to cut the overall vehicle weight by approximately 3 tonnes compared with conventional designs, thereby providing strong support for energy savings, reduced consumption, and improved operational performance.
Intelligence is another major highlight of this train. It features OLED smart touch‑screen windows; with a simple tap, passengers can instantly access route maps, transfer information, and local cultural and tourism updates. Wireless charging pads are also integrated beneath the handrails, further enhancing travel convenience. The incorporation of these smart devices places higher demands on the interior system’s spatial layout and integration capabilities. To meet this challenge, Jinchuang Group has adopted modular pre‑configuration and integrated placement to seamlessly integrate display and charging equipment with the passenger compartment space.
In addition to advantages such as lightweight construction and ease of integration, carbon fiber composites also excel in noise reduction and thermal insulation, better achieving a balance between train lightweighting and passenger comfort.
Interior fit-out is a systems engineering discipline that bridges safety, energy efficiency, and passenger experience. From materials R&D to structural design, and from module integration to end-to-end services, Jinchuang has infused nearly 40 years of rail transit interior‑fit‑out expertise into this “moving city card.” Jinchuang Group will remain committed to innovation, leveraging continuous technological advancement and reliable full‑chain service capabilities to contribute “Jinchuang wisdom” to the expansion and upgrading of China’s rail transit network, and to the global rail transit industry.
