Germany has unveiled a zero-emissions train that only emits water

Germany is set to introduce the world’s first zero-emission passenger train to be powered by hydrogen. The Coradia iLint only emits excess steam into the atmosphere, and provides an alternative to the country’s 4,000 diesel trains. Lower Saxony has already ordered 14 of them from French company Alstom, and more are likely to be seen around the country if they are judged a success, reports Die Welt.
