Focusing on the integrated innovation of rail transit vehicles centered on trains in terms of shape, human factors, structure, and experience, this research explores design principles and methods for multi-modal rail transit scenarios. The study covers vehicles including high-speed trains, intercity trains, subways, light rail, and trams, with attention to key technologies such as aerodynamic shapes, modular cabin layouts, inclusive human-machine interfaces, and the application of sustainable materials. Methodologically, it integrates industrial design engineering analysis, user behavior simulation, and scenario task modeling to establish a comprehensive design process from conceptual ideation and scheme iteration to engineering validation. Through prototype experiments and case studies, design guidelines focused on safety, efficiency, comfort, and aesthetics are distilled, promoting systematic enhancement of rail transit vehicles in both functional and experiential dimensions.
