NFR and IIT Guwahati Create Paint System to Combat Moss on Bridges

08 May 2025 CW Team

Northeast Frontier Railway (NFR), in collaboration with Indian Institute of Technology (IIT) Guwahati, has developed a specialised paint system to prevent moss scaling on railway bridges. This innovation is aimed at improving structural durability, lowering maintenance costs, and enhancing railway safety in humid and rain-prone regions.

The new paint addresses the recurring problem of moss and biofilm formation on bridge surfaces, a major challenge in the northeastern climate. These biological layers contribute to corrosion and degrade the structural integrity of bridges over time.

According to NFR, the paint system includes an advanced chemical formulation with functionalised coatings and exterior lamination that actively resists moss growth and corrosion. This solution not only protects the visual appeal of bridges but also contributes to sustainable railway operations by reducing the frequency and cost of maintenance.

The development is expected to set a benchmark for future technology partnerships focused on modernising railway infrastructure in the region. It is also anticipated to support long-term safety goals for India’s railway network by mitigating environmental wear and tear.

Tunnelling work has commenced for the 11.84-km Thane–Borivali Twin Tunnel, set to be India’s longest urban road tunnel, marking a key milestone in Mumbai’s infrastructure development.As per a post shared by Mumbai Metropolitan Region Development Authority on social media platform X, the tunnel boring machine (TBM) ‘Nayak’—the country’s largest single-shield hard rock TBM for an urban tunnel—was launched by Devendra Fadnavis on Tuesday. The event was attended by Eknath Shinde and Sunetra Pawar, among other dignitaries. A second TBM, ‘Arjuna’, is expected to be launched so..

Large Format Store Planned At M G Road Metro Station

M G Road station in Bengaluru is set to host the city’s first large-format commercial and experience space, with planning led by Bangalore Metro Rail Corporation Limited. BMRCL has invited proposals to develop and operate a central business district destination at the Purple?Pink Line interchange. The plan positions the station as a commercial hub designed to serve a broad commuter base across the city. The proposal is part of a broader effort to activate transit nodes commercially. Tender documents set a minimum monthly rental of Rs 0.944 million (mn), inclusive of GST, for the large-format..

Government Cancels Auction Of Eleven Critical Mineral Blocks

The government has cancelled the auction of 11 critical and strategic mineral blocks after receiving a poor investor response and failing to attract a sufficient number of qualified bidders. The decision represents a setback to plans to ramp up domestic exploration and production of critical minerals amid global supply chain disruptions and rising demand for materials used in clean energy and advanced technologies. The mines ministry issued an annulment notice setting out the reasons for the cancellations. The annulment notice indicated that the auction process for five mineral blocks was canc..
