BHUBANESWAR: After achieving the breakthrough of Tunnel-7 of the Khurda Road-Balangir line, the East Coast Railway (ECoR) has equipped it with advanced safety infrastructure in accordance with prescribed railway standards.
The 1,975-metre-long tunnel, located between Purunakatak and Charichhak in Boudh district, has been fitted with systems related to structural stability, fire safety, ventilation, electrical supply and emergency response to support passenger safety and train operations, ECoR sources said.
Special emphasis was laid on structural stability, fire safety preparedness, ventilation efficiency, electrical reliability and emergency response mechanisms to ensure passenger safety and smooth train operations. The tunnel has been provided with advanced mechanical, electrical and plumbing (MEP) systems installed as per approved designs and technical specifications. These systems are undergoing testing and commissioning, the sources added.
According to ECoR, the key features include high-capacity ventilation, fire-fighting arrangements, lighting and automatic emergency lighting, public address, CCTV surveillance, SOS emergency calling and a linear heat detection system.
The ventilation system is equipped with jet fans to maintain air quality and manage smoke movement during emergencies. Fire-fighting arrangements include hydrant lines, hose reels and fire extinguishers placed at designated points. The lighting system is supported by power backup and illuminated exit and directional signage.
The public address and CCTV systems are intended to enable communication with passengers and continuous monitoring of the tunnel. The SOS emergency calling system will allow passengers to contact the control room, particularly in areas with limited mobile connectivity. The linear heat detection system will monitor temperature levels inside the tunnel to enable early identification of fire hazards.
ECoR said all systems have been checked for installation and alignment. Functional testing is in progress and commissioning will be completed in phases.
Once operational, the tunnel is expected to improve connectivity on the Khurda Road-Balangir rail line and facilitate passenger and freight movement. The railway zone said the project is likely to support regional connectivity and development.
The installation of the safety systems was carried out under the supervision of ECoR general manager Parmeshwar Funkwal, the zone added.
