Description

B61D covers the structural design, construction details, and classification of railway vehicle bodies, including passenger cars, freight wagons, and specialized train units. This subclass encompasses bodywork components such as frames, walls, roofs, floors, doors, windows, couplings, and interior fittings that define the physical form and functional characteristics of rail vehicles. It includes provisions for different vehicle types—such as coaches, dining cars, sleeping cars, and cargo wagons—as well as safety and comfort features integrated into the body structure. Adjacent classes address propulsion systems (B61C), running gear and suspension (B61E), and control/braking mechanisms (B61H), whereas B61D focuses specifically on the vehicle envelope and body-level design elements.
