Web Desk: Switzerland has launched a groundbreaking pilot project that places solar panels between railway tracks. The initiative offers a new way to generate renewable energy without using farmland, forests or other valuable land.
The project sits near the village of Buttes. Trains continue to run normally over a 100-meter section of active railway that contains 48 solar panels between the rails. The system ranks among the first efforts to generate electricity directly from railway infrastructure while keeping rail services operational.
Swiss startup Sun-Ways developed the installation. Although the project remains small, it aims to determine whether railway networks can become a major source of renewable electricity.
Rail operators typically fill the space between tracks with gravel. Sun-Ways wants to turn that unused area into a productive energy asset.
The installation generates 18 kilowatts of power. It can produce about 16,000 kilowatt-hours of electricity each year. That output can meet the annual energy needs of several European households.
In addition, the project offers an alternative to large solar farms. Those facilities often require vast areas of land. If the trial succeeds, countries could expand solar power generation without covering farmland, mountain slopes or environmentally sensitive areas with panels.
The pilot began operations on April 24, 2025. Since then, it has attracted attention from energy and transportation officials across Europe.
Experts are closely tracking the project’s performance. They want to see how the system handles daily rail traffic while maintaining safety and efficiency.
Meanwhile, Sun-Ways has signed a cooperation agreement with France’s national railway operator, SNCF. The agreement gives SNCF access to production data, technical findings and operational feedback from the Swiss trial.
As a result, France could adopt the technology if the pilot delivers strong results.
Supporters argue that railway corridors offer a largely untapped source of clean energy. Europe and other regions already operate thousands of kilometers of railway lines. These networks could provide space for solar installations without requiring new land development.
At the same time, Switzerland faces increasing pressure to expand renewable energy production. Government officials and industry leaders view projects such as the Buttes pilot as potential tools for improving energy security and reducing carbon emissions.
For now, the project remains experimental. However, a successful trial could open the door to a new generation of solar-powered railways. It could also provide a model for countries seeking innovative ways to meet rising energy demand.
If the technology proves safe and cost-effective, the gravel strip between railway tracks could become a valuable source of clean electricity in the years ahead.
