French-based company Alstom has announced that the world's first hydrogen train, the Coradia iLint, reached another historic milestone in Germany. A bunch of these hydrogen fuel-cell trains have now entered passenger service along a 100% hydrogen train route in the country's Lower Saxony area. The use of hydrogen as a fuel for trains noticeable reduces the burden on the environment. The Coradia iLint trains will gradually replace 15 diesel trains serving in the region. With a range of 2,000 km (around 620 miles), the Coradia iLint model can run all day on just one tank of hydrogen. This emissions-free regional train emits only steam and condensed water while operating at a low level of noise. "Emission-free mobility is one of the most important goals for ensuring a sustainable future, and Alstom has a clear ambition to become the world leader in alternative propulsion systems for rail. The world's first hydrogen train, the Coradia iLint, demonstrates our clear commitment to green mobility combined with state-of-the-art technology," said Henri Poupart-Lafarge, CEO and Chairman of the Board of Alstom.
