Varanasi: Indian Railways has taken a historic step toward green energy with the commissioning of the nation’s first removable solar panel system installed between railway tracks at Banaras Locomotive Works (BLW), Varanasi. Inaugurated on August 15, 2025, the pilot project features a 70-meter stretch equipped with 28 solar panels, delivering a combined peak output of 15 kWp.
Innovative Design for Sustainable Transport
Unlike conventional solar setups, the new panels are mounted directly on concrete sleepers using epoxy adhesive and secured with rubber pads to endure the vibrations of passing trains. The removable design ensures easy maintenance and operational flexibility without causing disruptions to train movement.
Experts highlight that if this model is scaled up, it could generate nearly 321,000 kWh annually per kilometre. By making use of idle space between tracks, the Railways can avoid land acquisition costs, one of the biggest hurdles in renewable energy expansion.
Part of Railways’ Net-Zero 2030 Mission
The project directly supports Indian Railways’ ambitious target of achieving net-zero carbon emissions by 2030. It complements ongoing efforts such as rooftop solar installations on stations, workshops, and offices, as well as large-scale renewable power procurement.
Engineered entirely by the BLW team, the project demonstrates the Railways’ ability to innovate eco-friendly, locally developed infrastructure solutions that balance energy generation with operational efficiency.
Broader Implications for Renewable Energy
Officials believe that with large-scale adoption, solar installations on tracks can transform the Railways’ energy profile. By combining sustainability with cost savings, the initiative reflects India’s growing commitment to renewable energy in the transport sector. It also signals how state-run institutions can become global examples of climate-friendly infrastructure.
