A sliding wheel detector apparatus automatically detects a sliding wheel condition of a wheel of a passing train. The apparatus includes means for parsing the cars (and trucks thereof) and segregating the same into brake valve groupings. The apparatus also includes means for determining a ratio between a wheel being evaluated and the rest of the wheels in a brake valve group. A sliding wheel will be much cooler than a properly braking wheel, and a ratio threshold is selected to detect this difference in temperature and produce an alarm.
