Railways are considered as the safest mode of transportation. But, thousands of people die due to train accidents. Derail and collision occur every ninety minutes. More than 10,000 such accidents had occurred over last eight years. Human error, signal misperception, system failure, improper maintenance of tracks and points are considered to be the main reasons. Many of such major accidents happen that could have been completely preventable by controlling the train parameters. In this paper, a survey on various technologies such as Wireless Sensor network and Embedded system which could be efficiently used to prevent such accidents along with their advantages and challenges are presented so that enhanced
