To heighten the sensitivity of detecting the abnormality of a support part mounted in a rolling stock.SOLUTION: A rolling stock comprises a first to a fourth support part respectively arranged at four corners of a virtual square in a plan view, the first and fourth support parts being arranged on a first diagonal line of the virtual square, the second and third support parts being arranged on a second diagonal line of the virtual square. An abnormality detector of the rolling stock comprises a first angular speed acquisition unit for acquiring a first angular speed in the periphery of the first diagonal line, a second angular speed acquisition unit for acquiring a second angular speed in the periphery of the second diagonal line, and a determination unit for determining abnormality in the second or third support part on the basis of the first angular speed acquired by the first angular speed acquisition unit, and determining abnormality in the first or fourth support part on the basis of the second angular speed acquired by the second angular speed acquisition unit.SELECTED DRAWING: Figure 1

    【課題】鉄道車両に搭載された支持部の異常検知の感度を高める。【解決手段】鉄道車両は、平面視において仮想四角形の4つの角にそれぞれ配置された第1〜第4支持部を備え、平面視において前記第1支持部及び前記第4支持部が前記仮想四角形の第1対角線上に配置され且つ前記第2支持部及び前記第3支持部が前記仮想四角形の第2対角線上に配置されてなる。鉄道車両の異常検知装置は、前記第1対角線周りの第1角速度を取得する第1角速度取得部と、前記第2対角線周りの第2角速度を取得する第2角速度取得部と、前記第1角速度取得部で取得された第1角速度に基づいて、前記第2支持部又は第3支持部における異常を判定し、かつ、前記第2角速度取得部で取得された第2角速度に基づいて、前記第1支持部又は第4支持部における異常を判定する判定部と、を有する。【選択図】図1
