Accidents in railway lines include collision with snags, derailment and human losses due to movements of trains. Railway transportation is usually very safe for passengers, although railway accidents and train derailment still happen. To solve this problem, a railway security system is proposed in this article. Here Ad hoc Wireless Networks are employed, but implementation of these systems poses problems due to the length of railway lines. On the other hand use of Ad hoc Wireless Network promises a very interesting and practical option. With recent advances in wireless communication and in electronics, there has been a reduction in the price, power, and size of sensor nodes. There sensors include a microprocessor, a multi-byte RAM, a short-range, short-wave radio transmitter, and a small power source (like a battery).The main technique and the major aim of this system is to develop a new solution, based on a Adhoc Wireless Networks with the use of WiMAX(Worldwide Interoperability for Microwave Access) for the problems faced in railway lines. The purpose in studying railway lines includes finding new methods to reduce the rate of accidents. © Research India Publications.
