This railway vehicle is provided with: a bracket including a contact surface which is in contact with a second surface of a second plate member, and also including a recess which is provided in a portion facing an uneven surface; and a dynamic vibration absorber including a damper section which is located on the side opposite the contact surface and which is affixed to the bracket, and also including a weight section which is disposed on the side opposite the side to which the bracket is provided and which is disposed on the damper section. The bracket is separated from the uneven surface.

Railway vehicle

An anomaly determination device includes a changeover force measurement unit that measures a changeover force output by a driving device, the driving device outputting a changeover force for switching a direction of a branch rail whose direction is variable, a voltage measurement unit that measures a voltage supplied to the driving device, a current measurement unit that measures a current flowing through the driving device, and an anomaly determination unit that determines whether or not there is an anomaly in the branch rail, there is an anomaly in the driving device, and there is an anomaly in power supplied to the driving device on the basis of the magnitude of the changeover force, the magnitude of the voltage, and the magnitude of the current.
