B61B RAILWAY SYSTEMS; EQUIPMENT THEREFOR NOT OTHERWISE PROVIDED FOR (lifts or hoists, elevators, escalators, moving walkways B66B)
Introduced: September 1968
Description
B61B covers railway systems and associated equipment that do not fit within more specific railway classifications. This subclass encompasses auxiliary systems, infrastructure components, and integrated railway arrangements not classified elsewhere in B61, such as rail-mounted structures, railway-based transportation networks, and supporting mechanical systems. It serves as a residual classification for railway technology that falls outside the scope of dedicated subclasses for locomotives (B61C), rolling stock (B61D), track construction (B61F), or signaling and safety systems (B61L). Applications include comprehensive railway system designs, specialized railway equipment, and integrated solutions combining multiple railway technologies.
