A railroad vehicle bearing malfunction sensing system is provided which is able to accurately determine a malfunction of an axle bearing in each vehicle of a train. The system includes: a plurality of data loggers (5) mounted on a plurality of axle bearings (3), respectively, in at least one vehicle (2) of a single-line train (1), each logger (5) including: a detection/recording (12) to detect vibration of the bearing (3) and record detected vibration detection data; and a wireless communication (13) to receive a recording start command for starting recording of the vibration detection data by the detection/recording (12); and a simultaneous recording start command (22) to simultaneously and wirelessly transmit recording start commands to the loggers (5) respectively corresponding to the bearings (3).
