China’s rapid expansion of urban rail transit, particularly in lower-tier cities, has transformed the nation into a global leader in subway infrastructure. To make this growth sustainable and cost-effective, China has increasingly shifted toward domestic manufacturing of metro equipment, replacing costly imported systems. However, while domestically produced equipment now accounts for over 70% of metro systems, the lack of core technology and independent innovation remains a significant challenge. At HUIHE Circuits (https://www.hhcircuits.com/), we recognize the critical role of advanced PCB solutions—such as subway PCB, signal PCB, and metro PCB—in addressing these challenges and driving the localization of urban rail transit technology.
The Landscape of Metro Equipment Localization
Localization in the context of metro equipment encompasses two key aspects. First, it involves manufacturing critical components domestically or assembling imported parts within China. This includes equipment produced by foreign companies setting up local production facilities. Second, and more crucially, localization demands independent innovation in core technologies to reduce reliance on foreign systems. Achieving true technological independence—often referred to as “deep localization”—requires mastering the design and development of critical components like rail PCB and signal PCB, which are integral to metro systems’ safety and efficiency.
Despite significant progress, the localization of core technologies lags behind. For instance, in cities like Dalian, metro projects have achieved impressive localization rates: 100% for HVAC systems, 93% for power supply systems, 80% for vehicle procurement, and 70% for exit systems. However, many of these systems still rely on foreign technologies, particularly in critical areas like signaling. For example, metro lines in Nanjing and Guangzhou use Siemens-based signaling systems, while Shanghai’s Line 10 relies on Casco Signal Co., and Hangzhou’s metro incorporates technology from Alstom (USA). Even though these systems are assembled domestically, their core technologies often remain foreign, raising concerns about long-term reliability, safety, and cost.
Overcoming Technical Barriers with PCB Innovation
At HUIHE Circuits, we believe that breaking the monopoly of foreign technology starts with innovative approaches to PCB design and manufacturing. Our expertise in subway PCB and metro PCB production enables us to support the reverse engineering and re-innovation of critical metro equipment. By leveraging advanced PCB copy board techniques, we can extract detailed technical data—such as PCB files, BOM lists, and schematic diagrams—from foreign systems. This process allows us to replicate, adapt, and improve upon existing technologies, paving the way for localized solutions that meet the stringent safety and performance standards of urban rail systems.
For example, signal PCB designs are at the heart of metro signaling systems, ensuring precise communication and control. By analyzing and re-engineering these boards, HUIHE Circuits helps domestic manufacturers reduce dependency on foreign suppliers while enhancing system reliability. Similarly, drive PCB solutions are critical for powering metro vehicles and auxiliary systems. Our reverse engineering capabilities enable us to develop customized PCBs that align with China’s unique operational requirements, ensuring compatibility and cost efficiency.
Strategies for Advancing Core Technology Localization
To elevate the localization of metro equipment, China must prioritize a multi-faceted approach that combines independent innovation, integrated innovation, and the strategic digestion of imported technologies. Independent innovation, while challenging and resource-intensive, is essential for long-term technological sovereignty. Large enterprises with robust R&D capabilities can lead this charge, developing proprietary solutions for critical components like rail PCB and signal PCB.
However, for many companies, the introduction, digestion, and absorption of foreign technologies offer a faster path to innovation. At HUIHE Circuits, we specialize in this process through our advanced PCB copy board services. By meticulously analyzing foreign equipment, we extract critical technical data and re-engineer it to create localized solutions. This approach not only accelerates innovation but also ensures that domestic manufacturers can produce high-quality, cost-effective equipment tailored to China’s urban rail needs.
