CPC Subclass Not Allocatable
B60M POWER SUPPLY LINES, AND DEVICES ALONG RAILS, FOR ELECTRICALLY- PROPELLED VEHICLES (control of points and safety arrangements along railway lines B61L; construction of rails and points in general E01B)
Description
Covers infrastructure and apparatus for delivering electrical power to rail-mounted or track-guided vehicles, including overhead contact lines (catenary systems), third-rail systems, and associated supporting structures such as poles, insulators, and pantograph interfaces. Encompasses power distribution devices, connection mechanisms, and safety systems integral to the track-side power supply network for electric trains, trams, and similar vehicles. Excludes the vehicle's onboard electrical systems and power storage devices, which fall under related B60 subclasses.
