The authors proposed this paper based on data transmission through power line. And this communication is implemented in railways by transmitting data through it. In this they are using power line communication module, which is defined as -carrying data on a conductor and also used for electric power transmission. It acts as both transceivers with secure and fast condition. The above concept is exiting concept, now-a-days which are used in home appliances. Now the proposed concept is implemented in railways, by sending a data from junction to engine driver or vice versa. This process is done in a single line cable.
