 POWER SUPPLY LINES, OR DEVICES ALONG RAILS, FOR ELECTRICALLY-PROPELLED VEHICLES (control of points or safety arrangements along railway lines B 61 L; construction of rails or points in general E 01 B)
 

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.
