The objective of this paper is to implement smart ways to prevent railway accidents and to minimize the loss of life and money. Faulty equipment, improper maintenance of tracks and train conductor negligence are some of the causes of train accidents. The paper provides a way to detect the major cause of rail derailment which is the presence of cracks in rails. It eliminates most of the flaws in the current system of crack detection in railway tracks using IoT-based modern system, which can significantly reduce the cost, time and manpower without compromising accuracy. It also solves this problem by detecting the presence of cracks in rail and notifying the concerned railway authority about the location of the crack. The detection is performed using IoT-based modern system and transducer. Angle beam techniques are utilized employing common angle beam transducer assemblies aligned so as to direct sound energy into the test piece at selected angle; the administrator couples the transducer to the test piece and finds the refracted waves and after that utilizes Global Positioning System (GPS). Global System for Mobile (GSM) technology specialists are informed about the location of cracks.

 
 

Train accidents are not uncommon in India. In terms of reliability and safety parameters, global standards have not yet been truly reached. From 2003 to 2015, 239 accidents happened on the network of the Indian Railways (http://www.hindustantimes.com/india-news/with-239-accidents-in-the-last-12-years-why-are-trains-derailing-so-often/story-m4vVZrJXdHleyJpf2EdwMK.html) and 208 of these—or 80% of all accidents—happened because of derailments, says the parliamentary standing committee report presented on November 2016 (https://timesofindia.indiatimes.com/india/Indore-Patna-Express-train-accident-Rail-fracture-suspected-to-be-cause-of-derailment/articleshow/55523889.cms). The most recent derailment was Utkal Express derailment on August 18, 2017. At least 23 people were killed and over 40 others injured when 14 coaches of Puri-Haridwar-Kalinga Express train derailed in Khatauli in Uttar Pradesh’s Muzaffarnagar district. And the presence of cracks in tracks are the reasons behind these derailments. Figure 1 shows cracks in railway tracks. Because when tracks get fractured, they are not able to bear the weight of trains, or cannot sustain any sudden break, etc. and this results in derailment.
