Mizoram News: Tunnel communication system designed for Lumding section

An integrated tunnel communication system was designed to provide seamless radio communication between the base station of the tunnel control room and handheld radio inside the tunnel to the station masters of adjacent stations on the Bhairabi-Sairang new single line section of Lumding division of North Frontier Railway. Is.

RailTel, a PSU of the Railway Ministry, has received an order worth Rs 66.83 crore for supply, installation, testing and commissioning of integrated tunnel communication system, emergency call system in tunnels and IPIS (Integrated Passenger Information System) at stations. Bhairabi-Sairang new single line section of Lumding division of North Frontier Railway.

RailTel is a “Mini Ratna (Category-I)” Central Public Sector Enterprise, one of the largest neutral telecom infrastructure providers in the country, with pan-India optic fiber coverage covering many cities and rural areas of the country. Is the network.

The project will cover 32 tunnels with a total length of just over 12 kilometres.

Tunnel communication is very important and essential for the tunnel dominated part of Lumding Division.

Poor signal coverage causes communication disruptions inside the tunnels, which can hamper train operations and maintenance activities.

“The communication channels in the tunnel operate independently, simultaneously and without any risk of failure. Successful implementation of this system is important to ensure safety and efficiency of train operations in the challenging terrain of Indian Railways tunnels,” officials said.

The goal of this tunnel communications project is to establish continuous coverage along the entire length of the tunnel, ensuring clear audio without interruption.

The system guarantees reliable operation in the harsh environmental conditions within the tunnel, providing trunked radio channels in different bands.

“Additionally, the system boasts user-friendly operation and maintenance, contributing to a streamlined and efficient communication infrastructure within the tunnels. The Bhairabi-Sairang new line project is one of the most difficult sections, where problems of road, non-availability of materials, high cost of transportation, difficult terrain etc. make it a very challenging task to execute,” say officials. Is.

The project work includes provision of IT data networking infrastructure, PA and emergency/SOS call point systems, supply and installation of IP and IP-based CCTV surveillance system. In addition, design, supply, installation, wiring, testing and commissioning of integrated communication systems VHF (Simplex) and backbone networks for smart facilities and emergency communication systems are also included in the scope of work.
