RTOS provides for the use of semaphores for signaling, when the first train is start on the track, a signal is set as high priority (1) and the signal for the other train has low priority (0). The system ensures the reliability and accuracy of the train location using sensor modules.

PLCC technology uses advanced modulation techniques which imposes the data signal of high frequency over the low frequency power signal. To avoid the train collision, in case of two trains approaching in the same track at the same time oppositely with high speed which leads to collision. Train can collided due to human error and usage of faulty equipment. The goal of the system is to improve the mode of the communication (signaling), which is successfully avoiding the train collision using semaphore signaling and Power Line Carrier Communication (PLCC). Today train is the most widely used transport system but accidents are occurring due to collision and signal failure. Keywords: ARM Processor, Semaphore, PLCC (Power Line Carrier Communication), GSM, Track sensors On the other hand the warning signal and controlling signals to the train can also be transferred to the loco pilot using Power Line Carrier Communication (PLCC).Thus PLCC avoids signal cables nexus. GSM network transfer the data immediately to the control station from the station, alert signal is fed to the pilot and the collision can be avoided.

The location of the train is detected at various parts of same track and it transfers through GSM technology with the control of ARM Processor When two trains travel in same track the current location of the train is sent to the control station. This design makes an approach to improve the mode of communication (signalling) using ARM 8 processor and to avoid the train collision using semaphore signaling. In railways a single miscommunication in the signaling may lead to catastrophe. The signaling in the railways plays the vital role to direct the trains in a right way at right speed towards the destination. Abstract: Railway is the most economist mode for transport in the world.
