    Safety plays a prime importance in all aspects of life, especially in railway level crossings. Because accidents at level crossing contribute large portion on train accidents which costs human life and economical crisis. Moreover, the accident occur cause train delay and operational interruption. To tackle this problem and to assure safety by reducing accident at level crossing using various equipments used for this purpose. But existing warning device, and crossing barrier are simple train-oriented protection equipments. In this thesis, remote monitoring of level crossing to reduce those accidents to a minimum level to achieve safety at level crossing using wireless-SCADA System is proposed. SCADA system is employed to monitor level crossings. The system employed encompasses collecting of data from a number of remote terminal unit’s (RTU’s) and operator terminal ,and transferring it back to the traffic control center, carrying out any necessary analysis and control and then displaying that information on a number of operator screens or displays. The required control actions are then conveyed back to the process for taking action. In general, the SCADA system consists of two major parts, remote control center (RCC) and remote terminal unit’s (RTU’s).The RCC does the work of the a supervisor and controls the activities of a network through RTUs.
