Switzerland is pioneering an innovative approach to renewable energy by transforming the space between railway tracks into a functional solar power source. The initiative, led by the Swiss startup Sun-Ways, involves installing solar panels directly on an active railroad line without disrupting train operations or requiring additional land.
Currently underway in Buttes, located in the canton of Neuchâtel, this pilot project features a 100-meter قسم of track operated by TransN. Within this stretch, forty-eight photovoltaic panels have been positioned between the rails, resting securely on the railroad ties. Together, these panels deliver a combined installed capacity of 18 kW, effectively turning a traditional rail line into a distributed solar power plant.
Innovation Meets Practicality on Active Tracks
One of the standout aspects of Sun-Ways’ design is the removability of the solar panels. This flexibility is crucial in the railroad industry, which demands rigorous safety standards, frequent inspections, and ongoing maintenance. The panels can be swiftly lifted whenever necessary to allow track inspections, tie replacements, or other maintenance tasks, ensuring that energy generation does not interfere with the essential upkeep of the railway.
While the system does not directly power the trains themselves, it capitalizes on an otherwise unused area — the space between the rails — to generate electricity. This innovative use of existing infrastructure allows for the production of clean energy without encroaching on new land, a significant advantage in densely populated or environmentally sensitive regions.
The ongoing test in Switzerland serves as a proof of concept for integrating renewable energy solutions into conventional railway networks. By demonstrating that a standard rail line can double as a solar energy generator without affecting daily operations, Sun-Ways could pave the way for similar projects worldwide, combining transportation infrastructure with sustainable power generation.
