Claim Text:
1. A measuring apparatus of train wheel wear, the apparatus comprising: a speed measuring unit configured to measure a revolution of a train wheel and a speed of a train using a tachometer; a position measuring unit configured to measure a position of the train by receiving a position signal from a balise, wherein the position of the train is information on an absolute running distance of a running train; a calculation unit configured to calculate abrasiveness of the train wheel by calculating a size of the train wheel using the measured revolution of the train wheel, and the speed and the position of the train; a storage configured to store the calculated abrasiveness of the train wheel calculated by the calculation unit; and a display unit configured to display the calculated abrasiveness of the train wheel calculated by the calculation unit, wherein the storage stores a reference abrasiveness for warning a user that the calculated wheel size or the calculated abrasiveness of the train wheel is smaller than a reference size or is smaller than a reference abrasiveness, if the calculated wheel size or the calculated abrasiveness of the train wheel is smaller than the reference size or the reference abrasiveness, and wherein the display unit displays that the abrasiveness of the train wheel is smaller than the reference abrasiveness, if the calculated abrasiveness of the train wheel is smaller than the reference abrasiveness.
