Trains become more eco-friendly
Sustainable Innovation in Railway Transportation
How do you transform a train into a generator? By modifying the motor so it recovers energy generated by the brakes on downhill sections. The technology, which has been in use on Zermatt’s Gornergrat Railway since the late 19th century, is now being used between Salvan and Vernayaz on the Mont Blanc Express, which runs from Martigny to Chamonix. For the first time ever, the generated electricity will not only be used to power the train going uphill, it will also feed into the broader electric grid!
