POWER SUPPLY LINES, OR DEVICES ALONG RAILS, FOR ELECTRICALLY-PROPELLED VEHICLES (control of points or safety arrangements along railway lines B61L; construction of rails or points in general E01B)

Note

This subclass covers:

–

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 lines.

Power supply lines for contact with collector on vehicle (collectors therefor B60L 5/00)
