REGIONAL, December 23 2023: RailTel, a PSU under the Ministry of Railways, has received an order worth Rs 66.83 Crore for the Supply, Installation, Testing, and Commissioning of an Integrated Tunnel Communication System and Emergency Call Arrangements in Tunnels, as well as an Integrated Passenger Information System (IPIS) at Stations in the Bhairabi-Sairang new Single Line Section of the Lumding Division of the North Frontier Railway.
The poor signal coverage inside the tunnels can cause interruptions in communication, which can hinder train operations and maintenance activities. To address this issue, RailTel has designed a state-of-the-art Integrated Tunnel Communication System that enables uninterrupted radio communication between handheld radios inside the tunnel, the base station at the tunnel control rooms, and the Station Masters at adjacent stations.
Handheld devices are allocated to personnel involved in construction, maintenance, and train operations. The communication channels within the tunnel operate independently, simultaneously, and without any risk of failure.
The successful implementation of this system is crucial for ensuring the safety and efficiency of train operations within the challenging terrain of Indian Railway tunnels. 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.
The Bhairabi-Sairang new line project is one of the toughest sections, where challenges such as road access, material availability, high transportation costs, and tough terrain make it a very challenging project to execute.
The project includes the provision of Supply and Installation of IT Data Networking Infrastructure, PA & Emergency/SOS Call Points system, and an IP-based CCTV Surveillance System. Furthermore, the scope of work also includes the Design, Supply, Installation, Wiring, Testing, and Commissioning of an Integrated Communication System for VHF (Simplex) and a Backbone Network for smart facilities and Emergency Communication System.
RailTel is also implementing Tunnel Radio Communication projects for the Katra-Banihal section of the Northern Railway, the Panvel-Karjat, Karjat-Lonawala and Kasara-Igatpuri sections of the Central Railway, and the Castle Rock-Kulem section (Braganza Ghat) of the South Western Railway.
