Staff Reporter, Guwahati: In a groundbreaking move to improve railway infrastructure in the Northeast, the Northeast Frontier Railway (NFR) has teamed up with the Indian Institute of Technology (IIT) Guwahati to develop a cutting-edge paint technology designed to prevent moss growth on railway bridges. This innovative initiative, led by NFR’s Principal Chief Engineer Shri Sandeep Sharma and IIT Guwahati’s Dr. Vimal Katiyar, aims to address a longstanding challenge in the region’s humid and rain-prone climate. The project was initiated following the direction of Shri Chetan Kumar Shrivastava, General Manager of NFR, to find a sustainable solution to moss and biofilm accumulation that not only mars bridge appearance but also accelerates structural corrosion. The newly developed paint system features advanced chemical formulations that resist both corrosion and biological growth. With a specialized lamination layer, it offers enhanced durability and protection, promising to reduce maintenance costs and extend the lifespan of vital railway structures.This collaboration showcases the potential of industry-academia partnerships in solving real-world problems. By blending IIT Guwahati’s scientific expertise with NFR’s operational experience, the project sets a precedent for future innovations in infrastructure management. The initiative is a major step toward ensuring safer, cleaner, and more resilient railway bridges in one of India’s most challenging climatic zones.
