mission of carbon dioxide beyond a certain limit has been held responsible for global warming and resultant climate change. Means of transport are considered among the worst pollutants for the volume of carbon dioxide that they deposit in the atmosphere every year. Trains are relatively less pollutant compared to buses, cars and similar diesel-powered vehicles. Still, trains release huge amount of carbon dioxide.
Now for the first time in the world, a pollution-free train has been rolled out. This train runs on hydrogen power. They have batteries made up of lithium-ion, those similar to used in the mobile phones and many home appliances.
