Paper Title
Crack Detection and Collision Avoidance in Railway Using Arm Cortex

Most of the transportation and commercial activities are carried by railway network. Any trouble in this transportation increases crucial damage to the society also loss of human life. This proposed system is used to overcome the disaster from railway cracks and collision between two stations.The cracks are detected through IR sensor and Collisions are detected by the ultra-sonic sensor between two stations. Four wheel smart trolley is used in the place of train. One of the important thing in this project is created android application for generating the email for good documentary purpose. As soon as message received from GSM then mail has been composed by the android application and send it to the higher authority automatically for further proceedings. Keywords— ARM Cortex,IR sensor, ultrasonic sensor, GSM, Android Application.
