The comprehensive fine-scale simulation model for multiple-unit trains serves as a flagship practical training tool for rail transit institutions seeking to promote the integration of industry and education. It is deeply aligned with domestic rail transit industry position standards and meticulously developed using current mainstream multiple-unit trains as prototypes. It serves multiple purposes, including pedagogical understanding, on-the-job training, skill assessment, and joint school-enterprise training, thereby bridging the gap between classroom instruction and actual corporate positions. During the initial phase of the overall model solution, requirements from railway vehicle depots and passenger service sections were integrated simultaneously; consequently, the teaching content aligns with actual corporate operational workflows. The training modules cover four key professional areas: driver operations, vehicle maintenance, passenger service, and emergency response. A single set of training tools supports shared use across multiple disciplines, thereby enhancing the utilization rate of training laboratories. The toolset facilitates collaborative development of curriculum resources between schools and enterprises; corporate engineers can leverage the full-vehicle simulation model for order-based class instruction and retraining for existing employees, while faculty members can use the tool to develop modular training work orders, micro-courses, and training videos, enabling the joint construction and sharing of a teaching resource library. The model offers excellent scalability, with pre-reserved interfaces for signal systems, traction power supply, and onboard network systems; these can be upgraded in the future with virtual-real integration modules and paired with virtual simulation software to achieve linked teaching between physical models and digital simulations, creating a new hybrid virtual-real training model. The toolset features a clean and professional appearance with a strong visual impact for the entire vehicle. Beyond routine teaching, it can be used for professional admissions showcases, campus open days, and industry exchange visits, providing a direct demonstration of the institution's strength in rail transit education. The model offers a one-stop suite covering production, delivery, installation, and training; manufacturers provide on-site installation and commissioning, operational training for instructors, and regular maintenance services, thereby reducing the implementation difficulty for institutions when building new training facilities. This teaching aid aligns with the direction of modern vocational education reform, helping institutions establish high-level rail transit training bases, deepening the integration of school–enterprise cooperation, job requirements, curricula, competitions, and certifications, promoting the alignment and synchronization of talent cultivation standards for rail transit programs with industry job standards, and cultivating the interdisciplinary skilled talent truly needed by enterprises.
