Belgium has plans to power 170 trains by wind energy.
In total 25 turbines, located in different regions of the country will generate 35 million kWh of energy – equivalent to powering 10,000 homes.
About two-thirds of the electricity produced will be used for the rail line between Leuven and Liege and the surplus will be added to the domestic electricity supply grid.
The project will help reduce 15,000 tonnes of carbon emissions.
The first seven turbines started operating last weekend and the rest are expected to generate electricity by the end of the year.
