The introduced surveying system in this project is operational on both ballast and slab tracks. The system can be operated in tunnels without interruption. 'Crack Detection System for Railway Track by Using Ultrasonic and PIR Sensor' ISSN 2348 9928 IJAICT Volume -1, Issue-1, May 2014. This system comprises of GPS module, GSM modem, IR sensor, PIR sensor to bring into operation the crack detection, communication purpose and identification of any living being crossing the railway track.
Project Abstract / Summary: The 60% of accidents in railways are due to track problems which lead to derailment. This project presents the system for automatic crack detection in railway tracks.

This project can help to detect the cracks or breakages in railway tracks if any before the train passes and the alert signal is sent to the train operator and the power line is tripped off immediately. The automatic crack detection system is constructed using vibration sensors and MEMS technology. Vibration sensor is used to detect the crack which has speed response to vibrations. MEMS are used to detect the track deviations and dislocations. MEMS is Micro Electro Mechanical System that combines electrical and mechanical components.In this project MEMS are used to check the status of the railway tracks and RF modules are used to transmit and receive the signal. PIC micro controller is used to compare the input signals with threshold value at transmitter side.
MMIC (Monolithic Microwave Integrated Circuit) is used for continuous monitoring of MEMS. This project is cost effective and simple. Why did you choose to work on this project topic: The 60% of accidents in railways are due to track problems which lead to derailment.Derailment problem often result in loss of human lives and damage to property. To prevent such kind of accidents we chose to work on this project topic.
