Pollution concerns are prompting rail chiefs to convert trains to fuel-cell technology that gives off only water
Air pollution has always been a problem, especially in the industrialised world.
As part of continuing efforts to tackle the problem, Britain’s railways are to enter a new steam age with up to 100 commuter trains poised to be converted to run on eco-friendly hydrogen. Hence, hydrogen trains could be on the network within three years. They will be almost silent, with the same range and speed as traditional diesel and electric trains.
The trains' only emissions will be water, some of which will be released as small puffs of steam above the train. The conversion programme is set make Britain a world leader in hydrogen train technology.
There are plans to scrap Britain’s 3, 900 diesel trains by 2040.
