at the historic bo�*ness and kinneil railway, engineers have also moved on from the past and into technologiesowards cleaner rail travel. and this — this is the little train that could be powered by hydrogen. the train itself is not new. instead, this is where old technology meets new, and a test of where hydrogen power might be a viable option on our railways. the technology beneath my feet is relatively new for the railway, but one of the interesting things about this project is that this train is actually quite old, built in 1979, and it has been retrofitted to run on hydrogen. so, what was a class 314 headed for the scrapheap is now a class 614 hydrogen—powered train. the hydrogen is stored in tanks underneath the carriages along with the hydrogen fuel cell, which converts the hydrogen back to electricity which powers the train. all that is emitted is steam and water. the hydrogen needed to power the train is made on site. electricity from renewable sources is used to split water, creating hydrogen. that is then compressed, compressed again, and then stored, ready for refuelling the train.
