B61 RAILWAYS
Description
B61 encompasses the design, construction, operation, and maintenance of railway systems and infrastructure. This classification covers railway tracks, rail vehicles (locomotives, carriages, wagons), signalling and safety systems, coupling devices, and associated mechanical and electrical equipment for ground-based rail transport. It includes both conventional railways and specialized rail systems such as rack railways, funicular railways, and monorails, but excludes air-cushion vehicles and magnetic levitation systems which fall under separate transport classifications.
IPC and CPC are identically structured here. All 9 subcodes exist in both systems.
8 shared codes have differing titles between IPC and CPC.
