B60MPOWER 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 E01BThis subclass deals with: overhead, overground or underground power supply lines; their crossings and points, erection and supervision;devices along rails and rail joints, for current conduction and for insulation;safety devices along the route against earth currents and inductive interference with nearby communication linesIn this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
