Abstract
A rail break detection device to which an output waveform from a vibration sensor, which is a first vibration sensor, and an output waveform from a vibration sensor, which is a second vibration sensor, are input, the vibration sensors being mounted on different positions of rails, includes a waveform similarity determination unit to compare impulse waveforms separated from the output waveforms or compare continuous waveforms separated from the output waveforms, and determine similarity therebetween, and detects a break of a rail.
