Photovoltaics are still running after a year under Swiss trains

It is just over a year since a pilot project to install photovoltaics on a railway line kicked off. According to the CEO of Sun-Ways, the company behind the scheme, the challenge was not so much technical as regulatory. The project, a 100-meter photovoltaic installation on a railway line open to traffic, was inaugurated on April 24, 2025 in Buttes, Switzerland.
