Provided is a railway vehicle bearing abnormality sensing system that can accurately perform abnormality determination for railway vehicle bearings. The system (100) senses an abnormality in a plurality of rolling bearings (17) housed in an axle box (3) provided to a bogie (2). The system (100) includes: vibration detection devices (15) each detecting vibration of a rolling bearing; an analysis device (6) determining an abnormality in the bearings (17) on the basis of detection data detected by the device (15); and reception response detection start module (13) receiving a detection start signal and cause the device (15) to detect vibration of the rolling bearing. The system (100) further includes a measurement start command transmitting device (4), installed apart from a railway vehicle, transmitting the detection start signal to the module (13).
