Huge number of train accidents are to due to derailment which is a proven fact from the survey named “INDIAN RAILWAY ACCIDENTS STATISTICS -PERCENTAGE OF ACCIDENTS BY TYPE”. In period of 6 years between 2009 and 2014 there were 803 accidents in Indian Railways which killed 620 people and injured 1855 people. The Standing Committee on Railways, while examining safety and security in the railways they had noticed that more than half of the accidents are only due to lapses on the part of railway staff. Such lapses include carelessness in working, poor maintenance work, adoption of short-cuts and non-observance of laid down safety rules and procedures. The committee had recommended that a regular refresher course for each category of railway staff should be conducted. This can be minimized by reducing the manual based crack checking and replacing it with equipment-based crack detection. The proposed model is a simple system based on the voice tracking. Healthy track frequency is obtained and saved as reference signal.MSP-SA430SUB1GHZ is the spectrum analyser used to analyze the obtained frequency spectrum from the voice recorder. Voice recorder is placed in the trolley and provides voice recording which is further converted to frequency through spectrum analyzer. The deviation of the obtained frequency from the reference frequency beyond allowable range will be regarded as presence of crack. GPS location tracker will track the location at which crack is observed GSM module is used to transmit the location through SMS.
