Indian Railways Installs First Removable Solar Panels Between Active Tracks

In a landmark move towards sustainability, Indian Railways has rolled out India’s first removable solar panel system installed between active railway tracks. The initiative is part of the railway’s broader vision to achieve zero energy consumption in its infrastructure and promote the use of renewable energy for environmental protection.

The pilot project has been launched in the East Central zone using an indigenous design that allows the laying of solar panels between railway tracks without disrupting train operations. The panels are both durable and removable, allowing for easy maintenance and seasonal adjustments.

A senior railway official shared that Banaras Locomotive Works (BLW) has commissioned this trial installation. The pilot includes a 70-metre track fitted with 28 solar panels, generating 15 kWp of power, with an overall energy density of 240 kWp per kilometre and the potential to produce 960 units per day per kilometre.

Challenges and Solutions

Installing solar panels between active tracks required overcoming several challenges:

• Vibration: Train movements cause vibrations that may damage solar panels. To counter this, rubber mounting pads were used to absorb shocks.

• Fixation: Instead of traditional clamps, epoxy adhesive with strong metal-concrete bonding was applied to secure panels on concrete sleepers.

• Dust and Debris: Panels will need regular cleaning to maintain efficiency.

• Safety and Security: With concerns over theft and vandalism, CCTV surveillance systems have been installed.

• Easy Removal: To allow regular track maintenance, panels are fixed with four stainless steel allen bolts, making them easy to remove and reinstall.

Indian Railways and Renewable Energy

Indian Railways has been actively expanding its renewable power capacities. According to Rajya Sabha data (as of February 2025), the railway has installed 553 MW of solar capacity, 103 MW of wind energy, and 100 MW through hybrid systems.

By 2030, Indian Railways’ traction power demand is expected to reach 10,000 MW. So far, it has already secured 4,260 MW of installed solar capacity and 3,427 MW of wind capacity to meet its energy requirements.

This innovative step marks a significant milestone in the country’s journey towards green transportation, aligning with the Government of India’s push for renewable energy and climate change mitigation.
