Train to Train Communication using Wireless Network

Abstract: Today�s progressive railroads find themselves compelled to consider a CBTC upgrade because of its promises of increased safety, reliability, availability and associated reduction of maintenance costs; increased system capacity using the same civil infrastructure and its ability to reduce downtime during an upgrade. The urban rail transit systems has rapidly developed around the world, and due to increasing traffic pressure, there is a high demand to improve the efficiency of rail transit system. Communication based train control (CBTC) network is an automated control network for railways that ensures the safe and efficient operation of rail vehicles using data communications.
