In a rail fracture decision system (10) and a method for deciding rail fracture using the rail fracture decision system (10). The rail fracture decision system (10) includes a measuring position setup part (100), a signal measuring part (200), a data processing part (300) and a decision part (400). The measuring position setup part (100) is configured to determine a plurality of measuring positions having a reference point, and the measuring positions are different from each other. The signal measuring part (200) is configured to measure vibration signals at each of the measuring positions, when a train passes through the measuring positions having the reference point. The data processing part (300) is configured to calculate a maximum value at a predetermined frequency range on the measured vibration signals. The decision part (400) is configured to calculate variation of the vibration signals at the measuring positions, based on the calculated maximum values, and to decide whether a rail is fractured at the reference point.
