Solar without new land<\/h2>\n\n\n\n
The idea sounds simple at first. Instead of covering fields, rooftops, or parking lots<\/a>, Sun-Ways places photovoltaic panels in the unused strip between two rails, right on top of the sleepers that support the track. The company describes it as a \u201cworld first\u201d removable solar power plant placed between rails.<\/p>\n\n\n\n The panels are not meant to become permanent obstacles for rail crews. They can be taken out when workers need to inspect, weld, or repair the line, which is a crucial point in a sector where safety rules leave little room for improvisation.<\/p>\n\n\n\n The pilot was launched on April 24, 2025, with 48 solar panels rated at 380 watts each, giving the installation 18 kWp of capacity. Small? Absolutely, but the real question is not whether this short stretch can power a city. It is whether rail corridors<\/a> can become clean-energy corridors without taking more land.<\/p>\n\n\n\n The most striking result so far is not the electricity figure. It is the fact that thousands of trains have rolled over the installation without reported disruption. Scuderi told Swissinfo that the system had proved \u201cperfectly stable and safe\u201d during train passages.<\/p>\n\n\n\n There was also a surprise on cleaning. Sun-Ways had first imagined using a cylindrical brush mounted to the back of a train to sweep dust from the panels, but Scuderi said passing trains create enough airflow to carry the dust away. On that section, trains reach up to about 55 mph.<\/p>\n\n\n\n Maintenance was another concern. According to Scuderi, a module made of three panels about 20 ft. long can be detached from the track and disconnected from the grid in about 10 minutes with dedicated tools. That matters when crews need access quickly, not after a long shutdown.<\/p>\n\n\n\n TransN<\/a>, the public transport operator for the Buttes section, has also reported no conflict with everyday railway operations. Spokesperson Aline Odot told Swissinfo that there had been no issues with infrastructure, maintenance, or train traffic.<\/p>\n\n\n\n One concern often raised around solar near transport corridors is glare. So far, TransN says it has received no reports from its staff about glare affecting drivers, though that does not end the need for longer monitoring.<\/p>\n\n\n\n This is where the pilot gets interesting. A solar farm can look successful on paper, but railways are rough places, full of vibration, snow, dust, tight schedules, and strict maintenance needs. The trouble is, renewable energy has to work in the real world, not just on a drawing board.<\/p>\n\n\n\n France\u2019s SNCF Group is now following the project closely. In February 2026, the French railway company said it was joining forces with Sun-Ways to study movable solar equipment between rails on working passenger lines, with the Buttes pilot expected to run through 2028.<\/p>\n\n\n\n SNCF says its teams are looking at panel installation, glare, track inspection, maintenance impacts, power output, and dirt buildup. That is not a casual checklist. It is the kind of test rail operators need before letting any new equipment sit inside a live transport system.<\/p>\n\n\n\n The potential prize is large. Swissinfo reports that SNCF is responsible for about 17,400 miles of railway lines and plans to cover 20% of its energy consumption with photovoltaics<\/a> by 2030. If the Swiss pilot keeps performing, the idea could move from curiosity to infrastructure strategy.<\/p>\n\n\n\nAlso Read: A submarine fires a ballistic missile from deep underwater and the weapon never gets wet: the hidden trick that makes it possible<\/a><\/h4>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n
