Railway accidents would result countries and people in huge losses, carrying out the accident emergency rescue, rescuing the injured, depressing losses caused by the accident and the restoration of normal operations so inseparable from the railway emergency communications. When the accident occurred. At present, Chinas railway emergency telecommunication largely depends on the call interval columns, only could give a very simple business transmission, the speed is slowing, insufficient capacity, and the effect is not ideal, it is not conducive to the railway emergency rescue work development smoothly. To ensure the safety of rail transport and train operation, needing for planing and designing railway emergency telecommunication roundly. In this paper, we carried out a detailed demand analysis for the railway emergency telecommunication. The article for building a technologically advanced and well-constructed railway emergency telecommunication. From the several aspects of network architecture construction of Emergency command center, access way construction, the equipment selection and Tunnel construction of emergency telecommunication to plan and design. Railway Emergency communication should use an access way of wired and wireless, which take full advantage of basic communication facilities to ensure effective transmission of various services. Configuring the transmission channel equipment and terminal equipment according to local conditions, to ch
