At the recently concluded InnoTrans trade fair in Berlin, Germany unveiled the first ever hydrogen powered passenger train – a zero emission wonder that will be in operation from Dec 2017 and on-wards. Developed by the French company, Alstom, the ‘Coradia iLint’ train created quite a green stir in the world. Switching public transport to greener, more sustainable modes is on the agenda of most nations. And Germany seems to have flagged off this carbon free passenger train with great aplomb.
