The 15th International Trade Fair for Transport Technology, known as the "Olympics" of the global rail transit industry, was grandly held in Berlin, Germany from September 22 to 25. During the event, VELLINK, China's first embodied intelligence digital metro train developed by CRRC Changchun Railway Vehicles Co., Ltd., was officially unveiled, marking a significant technological breakthrough in China's urban rail transit equipment sector.

VELLINK, the embodied intelligence digital metro train, is targeted at the future of rail transit technology, and establishes a new development paradigm for urban metros with the "digital and intelligent, green, and people-centered" characteristics. It provides a brand-new solution for the upgrading and the green and smart transformation of global urban rail transit equipment. The full-size train unveiling was crowded with people. Upon its debut, VELLINK became a major highlight of the event, attracting great attention from professional visitors from different countries.

"This is the world's first train equipped with embodied intelligence technology. Relying on cutting-edge technologies such as an integrated sensing network, self-developed AI algorithms, and high-speed communications, the train is endowed with life-like capabilities of 'intelligent perception, decision-making, and interaction,' achieving an upgrade from passively executing instructions to actively optimizing operations," said Yin Hang, the train design manager.

At the intelligent perception level, the train is equipped with multi-dimensional heterogeneous devices such as radar, high-definition cameras, and sensors. Meanwhile, through a multimodal large model for perception, the train can perceive its line environment and operating status in real time, and anticipate changes in track conditions and equipment status. For intelligent decision-making, it can achieve collaborative interconnection through "train-to-train communications." Built on an onboard edge computing platform and powered by Zhuolun (Aizor), the industrial AI model independently developed by CRRC Changchun Railway Vehicles, VELLINK enables AI-based driving strategy, making urban rail transit capacity allocation more scientific and efficient. In terms of intelligent interaction, the train is equipped with an all-scenario intelligent interaction system. The driver's console applies technologies including smart display, holographic projection, and biometric identification, to further enhance driving safety and comfort.

VELLINK's joint development was led by CRRC Changchun Railway Vehicles in collaboration with Chengdu Rail Transit Group and other partners. It has achieved breakthroughs in multiple key core technologies, integrating multiple advantages such as embodied intelligence, integrated reconstruction, digital twin technology, green and low-carbon operations, and premium user experience. It further showcases China's cutting-edge technologies in urban rail transit equipment, providing a new model of green and intelligent development of global rail transit.
