Abstract: There is provided a configuration that can precisely detect abrasion of brake shoes of a railway vehicle. A brake shoe abrasion detection unit includes: at least one abrasion detection RF tag that is attached at a position of an abrasion limit of a brake shoe of a railway vehicle tread brake or a position closer to a braking surface than the abrasion limit; and a reference RF tag that is attached at a position beyond the abrasion limit of the brake shoe.

Abstract: There is provided a configuration in which an association between a location of each brake shoe of a railway vehicle and each abrasion detection tag is easily learned, and system implementation and management are simplified. A brake shoe abrasion detection system of a railway vehicle includes a computer that receives data of a signal read by a reader from at least one abrasion detection RF tag attached to each of a plurality of brake shoes of the railway vehicle passing the reader. The computer determines an association between a plurality of the signals and the plurality of brake shoes based on an order that the reader reads the plurality of signals from a plurality of the abrasion detection RF tags attached to the plurality of brake shoes, respectively.
