What device on the side of electric equipment collects electric power from the Third Rail by means of a sliding contact?

Explanation:
Power is collected from a third-rail system by a sliding contact mounted on the side of the electric vehicle. This device, the third rail shoe, rides along the energized third rail and conducts current into the locomotive’s traction and electrical systems. It’s typically made of carbon to resist wear and is spring-loaded to maintain a steady, reliable contact despite rail wear, debris, or track irregularities. The shoe is the actual pickup mechanism; other choices refer to different concepts (for example, the return path through the rail, a non-related term, or a safety warning device).
