RailTel, a PSU of Ministry of Railways, has received an order of Rs. 66.83 crore for supply, installation, testing and commissioning of Integrated Tunnel Communication system, Emergency Call Arrangements in tunnels & IPIS (Integrated Passenger Information System) at stations in Bhairabi- Sairang new single line section of Lumding Division of North East Frontier Railway.
The PSU said that communication inside the tunnels is interrupted due to poor signal coverage, which can hamper train operation & maintenance activities. The integrated tunnel communication system is designed to provide uninterrupted radio communication between handheld radios inside tunnel, to the base station at tunnel control rooms and station masters of adjacent stations.
It added that this tunnel communication project aims to establish continuous coverage along the entire tunnel length, ensuring clear audio without interference. The system guarantees reliable operation in the harsh environmental conditions within the tunnel, providing trunked radio channels across various bands. Additionally, the system boasts user-friendly operation and maintenance, contributing to a streamlined and efficient communication infrastructure within the tunnels.
Bhairabi- Sairang new line project is one of the toughest sections where problem of road approach, non-availability of materials, higher cost of transportations, tough terrain etc makes it a very challenging work to execute.
The project work includes provision of supply and installation of IT data networking infrastructure, PA & Emergency/ SOS Call Points system, IP based CCTV Surveillance System. Furthermore, design, supply, installation, wiring, testing and commissioning of integrated communication system VHF (Simplex) and backbone network for smart facilities & Emergency communication system are also included in the scope of work.
