Rail Track Measurement

The irregularities present in the track are the primary causes of vibration and these should be identified and the faults rectified to increase the safety of train travel. In this paper, a differential evolution technique based track measurement system is proposed to measure the health of the track. The abnormality of the track has been measured using micro electro mechanical system accelerometers which are mounted in the axle box. A new sensing method is used to estimate the exact location of the irregularity even when the signal is absent.
