1. A flat wheel detector, comprising:

  • a first sensor configured to be located adjacent a rail of a railroad track, the first sensor being oriented at a first angle relative to a horizontal plane;

    a second sensor configured to be located adjacent the rail, the second sensor being oriented at a second angle relative to the horizontal plane;

    a speed detector located adjacent the railroad track and configured to generate a signal indicative of a speed of a railroad car travelling on the railroad track; and

    a controller in communication with the first sensor, the second sensor, and the speed detector, the controller being configured to;

    receive signals from the first sensor, the second sensor, and the speed detector;

    adjust a threshold for a flat wheel condition based on the signal indicative of the speed; and

    detect a flat wheel on the railroad car when a parameter based on at least one of the signals received from the first sensor and the second sensor exceeds the threshold.
