Banaras Locomotive installs India's first removable solar panels on railway tracks; boosting green energy drive
The project was inaugurated by General Manager Naresh Pal Singh on Independence Day.
The pilot project involves installing removable solar panels on the sleepers—the support beams beneath the tracks. Commissioned on Line No. 19 of the BLW workshop, the initiative uses an indigenously designed installation procedure to mount solar panels without disrupting train traffic. The panels can also be removed easily whenever track maintenance is required.
The initiative aligns with
Indian Railways
' vision of promoting renewable energy and climate change mitigation. The GM praised Chief Electrical Service Engineer Bhardwaj Chaudhary and his team for the achievement, noting that the project complements existing rooftop solar power plants in BLW premises. 'This project is not only a new dimension in solar energy utilisation but will also serve as a robust model for green energy generation in Indian Railways in the future,' Singh said.
To address technical challenges, rubber mounting pads were used to reduce vibrations caused by passing trains, while epoxy adhesive was applied for strong fixation of panels to concrete sleepers. The panels are designed for easy cleaning and can be detached with just four SS Allen bolts for regular track work.
The pilot covers 70 metres of track with a 15 KWp installed capacity using 28 panels. It offers a power density of 220 KWp per kilometre and an energy density of 880 units per kilometre per day.
Each panel measures 2278 × 1133 × 30 mm, weighs 31.83 kg, and has a module efficiency of 21.31% with 144 half-cut monocrystalline PERC bifacial cells.
With Indian Railways' network spanning 1.2 lakh kilometres, officials said the technology could be widely deployed on yard lines without the need for land acquisition, as it uses the space between tracks. The estimated capacity is 3.21 lakh units per kilometre per year.
BLW said the innovation marks a major step towards the Indian Railways' target of achieving net zero carbon emissions.

CISF to recruit 70,000 jawans over 5 years
Kolkata: The Central Industrial Security Force (CISF) will recruit 70,000 jawans over the next five years to take the sanctioned strength to 2,20,000. The force inducted 13,230 personnel in 2024 and aims to recruit an additional 24,098 in 2025. There is a special emphasis on attracting more women candidates to promote gender diversity within the force. "As India continues to experience rapid economic growth, the demand for robust security across various critical sectors has become paramount. CISF, known for its specialised security services, will see expanded deployment in key areas such as the aviation and port sectors, thermal and nuclear power plants, and vital installations including hydropower plants. This expansion is particularly timely as new industrial hubs are anticipated to emerge in regions previously affected by left-wing extremism, such as Chhattisgarh, necessitating a fortified security presence," said an officer.
