In the foggy condition the loco pilot can’t able to see the signals,so we made a smart system which uses a low power high range radio signals to transmit the signal between station master,macl signal and loco pilot cabin.our system uses a special data packets for effective communication between the devices.this data packets carry the information like train parameters, loco pilot parameters(vcd) etc.vigilance control system helps in identifying the alertness of loco pilot.the smart signaling uses the current technology of railways like axle counter and macl signals for effective usage of data produced by them.this results in real time monitoring of various parameters of rolling stock and macl signals.the use of axle counters in rail yard management software which uses data from various occupancy to switch and prevent the traffic routes.this system does not need internet connectivity for transmission of data from train to station master cabin.display panels are provided at both place of station master room and loco cabin.this shows the real time details of various parameters.some of the components used in our system are relays , radio transceiver system.the main aim of our project is to increase the operation of railways in various climatic conditions. we have designed our system on the objective of “one solution to solve various problems”.as a result of it our smart system also helps in solving the various problems like unmanned level crossing and manned level crossing,alertness of the loco pilot while driving,real time monitoring of various parameters in operation of train.
