Abstract: A current collector monitoring system in one aspect of the present disclosure is provided with: a collected current measurement unit; a collected current state determination unit; an image acquisition unit; an event recognition unit; an event determination unit; and a determination result output unit. When a state of collected current corresponds to an abnormal state, the image acquisition unit acquires an image including, within an angle of view, a collector shoe provided to a current collector.

Abstract: An object of the present invention is to realize a structure able to well retain contact performance between an overhead line and a slider 7b, across the entire lengthwise direction of the slider 7b. The slider 7b formed of slider elements 34a and 34b divided in the crosswise direction of a vehicle, is supported on the upper surface of a slider support body 9. A center support member 12 forming the slider support body 9 is elastically deformed downward in a concaved shape across the longitudinal direction, due to a load applied due to contact between the overhead lines and the slider 7b. Also, together with this, both ends of the center support member 12 are supported on a shoe body 3a so as to allow free oscillation via the respective end section support members 13.
