IRCON Launches OWG

Katni (Metro Rail News): On February 22, 2025, IRCON successfully launched a 91.4-meter, 565-metric-ton open web girder for the Katni Grade Separator project using the side-slewing method. The girder was positioned over three operational Indian Railways tracks within 1 hour and 40 minutes, within the allotted 3-hour traffic and power block on existing running tracks.

IRCON Executes Girder Launch in Coordination with SECR

The IRCON’s team for the Katni Grade Separator project, in coordination with South East Central Railway’s Bilaspur division officials, successfully carried out the girder launching operation within the allotted block period. The process was executed smoothly while ensuring compliance with all safety protocols

Gkedv8lbcAAVceA

The completion of the open web girder installation is a crucial milestone for the Katni Grade Separator project. This project involves constructing a 15.85 km rail-on-rail viaduct, which is designed to separate train movements at different levels.

Gkedv8lbcAAVceA 1

The newly launched 91.4-meter open web girder serves as a crucial link between the east and west sections of the up-line viaduct. This connection allows trains to travel across Katni City without passing through the congested yards of Katni Junction. By creating a direct, uninterrupted route for passenger and freight trains, the grade separator is expected to enhance rail traffic flow in the region. The successful launch of this girder brings the project closer to completion.
