A rail track switching system has been designed to control railway track controlling devices including railway switches and signals within a given area from a single point. Such control is exercised through the use of various track circuits which detect the presence of trains on a particular track and monitor the train’s safety from a central room. The system secures the safety standards as well as economical and beneficial switch and signal control within a distance maintaining reliability, sensibility and precision. This research is based on microcontroller to reduce the complexity and cost. A low power dc motor is used as a track switching device. In the sensing unit photodiode is used for detecting IR radiation which ensures a reliable detection of trains’ entrance. A communication line communicates between the track switching device and main monitoring room. Total system can be monitored and visualize by a software which shows train’s position, operation mode and safety status. This system can work both automatically and manually and also can be controlled by the software from the main control room which gives the system more flexibility in operation.
