As integral components of Beijing’s rail transit network, the newly operational Fangshan and Yizhuang lines not only provide efficient public transportation but also drive urban and regional economic development. Leveraging nearly two decades of practical expertise, Huafei Technology seamlessly integrated its products into the AFC systems of both lines. Engineers conducted nighttime debugging to ensure "operations remain unaffected during upgrades, and upgrades do not disrupt operations", achieving a perfect alignment between technological capabilities and project requirements.
