In what's thought to be a world first, around 100 older trains are to be converted to run on Hydrogen power with the work being carried out at a site in Widnes.
Transport company Alstom who opened a site on Lovel Lane back in 2017 are leading the project which will see older trains re-engineered.
Alstom say the new project will create jobs in the local area and if it's successful could lead to bigger projects down the line.
Trains that run on Hydrogen emit no harmful emissions meaning they can be used on non electrified lines without polluting the air like a diesel train would.
Mike Muldoon from Alstom said "The process we are going to follow is to upgrade existing trains in Britain to create modern hydrogen units that can operate across the country.
"We envisage continued production and expansion here in Widnes"
Andrew Jones MP, UK Rail Minister. said “Hydrogen train technology is an exciting innovation which has the potential to transform our railway, making journeys cleaner and greener by cutting CO2 emissions even further.
"We are working with industry to establish how hydrogen trains can play an important part in the future, delivering better services on rural and inter-urban routes,”
It's not yet clear where the trains will operate when they are complete but it's thought the North of England is a contender.
