1. A railway vehicle bearing abnormality sensing system for sensing an abnormality in a plurality of rolling bearings housed in at least one axle box when the railway vehicle runs on travelling rails, the railway vehicle including at least one bogie, the at least one bogie including the at least one axle box, one or more of the plurality of rolling bearings being associated with one of the at least one axle box, the railway vehicle bearing abnormality sensing system comprising:

  • a plurality of vibration detection devices each configured to detect vibration of an associated one of the plurality of rolling bearings;

    an analysis device configured to determine an abnormality in the rolling bearings on the basis of pieces of detection data, each piece indicating the vibration of the rolling bearing detected by the associated vibration detection device;

    a plurality of reception response detection start modules connected to the vibration detection devices, respectively, each reception response detection start module causing the connected vibration detection device to detect vibration of the associated rolling bearing when receiving a detection start signal; and

    at least one measurement start command transmitting device installed apart from the railway vehicle and configured to transmit the detection start signal to the reception response detection start modules.
