A hydrogen fuel-cell passenger train developed by Swiss rail vehicle maker Stadler Rail has achieved a new Guinness World Record, traveling for almost two days around the clock for a distance of 1,741.7 miles.

Efforts to clean up dirty trains are already well underway, with heavy investment in electrifying networks around the world as well as rolling out battery-electric locomotives such as the FLXDrive, the Blues train and the Flirt Akku.

That last example is made by Stadler Rail AG, and managed to achieve a Guinness World Record in 2021 for the longest per-charge battery-only journey of 224 km (~140 miles), on a route between Berlin and Warnemünde during a freezing local winter – not bad for a train that was designed with an operational per-charge range of 80 km.
