India’s First Vertical Lift Rail Bridge: A Blend of Progress and Criticism
The New Pamban Bridge connects the mainland to Rameswaram Island with state-of-the-art engineering, though lapses have been flagged.
India’s first vertical lift railway sea bridge, the New Pamban Bridge in Tamil Nadu, is set to redefine connectivity between mainland India and Rameswaram Island. Railways Minister Ashwini Vaishnaw shared visuals of this engineering marvel, highlighting its modern design and operational advantages over its predecessor, the iconic Pamban Rail Bridge built in 1914. While the new bridge promises faster and safer travel, it has not been without its share of controversies and criticisms.
Features and Functionality
The New Pamban Bridge spans over two kilometers and incorporates a vertical lift mechanism, providing a 54-meter vertical clearance for maritime traffic, a significant improvement over the old bridge. Designed for speeds of up to 80 kmph, its maximum permissible speed has been capped at 75 kmph by the Commissioner of Railway Safety (CRS). Southern Railways expects to commence operations within the next two weeks following clearance conditions.
Historical Context and Transition
The old Pamban Bridge was a technical marvel of its time, serving as a vital link for 105 years. However, increasing corrosion led to its decommissioning in December 2022. The new structure, built with advanced engineering techniques, represents a step forward in connectivity and innovation, yet its execution has drawn criticism.
Criticisms and Safety Concerns
The CRS has flagged several lapses in the new bridge’s planning and execution. Key issues include:
• Non-Standard Design: The lift span girder was reportedly designed using non-standard codes, bypassing RDSO (Railways Standards Organisation) norms.
• Substandard Welding: Faulty welding techniques may have reduced the bridge’s stress-carrying capacity by 36%.
• Flouting Guidelines: The Railway Board has been criticized for excluding RDSO from the project, violating its own guidelines.
Despite these challenges, the CRS has authorized operations with stipulations, requiring Southern Railways to rectify deficiencies and report compliance.
Significance and Future Outlook
The New Pamban Bridge stands as a symbol of progress, connecting regions and communities with cutting-edge technology. However, its development highlights the need for stringent adherence to safety and quality standards in infrastructure projects. As the Southern Railways addresses the flagged concerns, the bridge is poised to become a key transport link, furthering India’s push for modern infrastructure.
For visitors and engineers alike, the bridge remains a sight to behold, a confluence of natural beauty and human ingenuity. Its inauguration will mark a new chapter in India’s rail and maritime history.
