A rail state monitoring apparatus 1 includes: a plurality of detection devices 2 provided on a train that travels on left and right railroad rails forming a track, and a processing device 3. The train is composed of one or a plurality of vehicles. For each of the plurality of detection devices 2, the detection device 2 has a magnetic sensor unit group 77 that is one or more magnetic sensor units facing the railroad rail, the magnetic sensor unit detects a peculiar point when the magnetic sensor unit passes over the peculiar point on the railroad rail, and the detection device 2 outputs a signal based on a result of the detection by the magnetic sensor unit group 77. The plurality of detection devices 2 include detection devices provided symmetrically on right and left sides of the train and/or detection devices provided on front and rear sides of the train. The processing device 3 receives signals output respectively from the plurality of detection devices 2, and discriminates whether the peculiar point is a rail seam point or a rail fracture point, based on a detection signal based on the signals from the plurality of detection devices 2.
