Poland has taken a groundbreaking step toward a cleaner and more sustainable future with the launch of its first hydrogen-powered train, a move set to reshape eco-friendly travel and redefine public transportation in one of the country’s most scenic regions.
On September 3, rail operator Koleje Dolno?l?skie introduced the SM42-6Dn locomotive, developed by PESA in Bydgoszcz, marking a milestone for Polish rail innovation. The train had undergone extensive testing throughout August before making its official debut. According to Hydrogen Central, “Operating on the scenic Jelenia Góra-to-Karpacz route, this eco-friendly train is set to redefine green travel in Poland.”
The hydrogen-powered machine runs on a combination of hydrogen fuel cells and electric batteries, producing zero emissions over its 10-mile (23-minute) journey near the Czechia border. During operation, the train emits only water vapor, eliminating the need for diesel engines or overhead electrical wiring. This not only cuts costs but also prevents heat-trapping gases from entering the atmosphere.
After its inaugural run, further trials were conducted to evaluate whether the technology could be scaled for broader use across the country. The SM42-6Dn was also showcased at the Annual Economic Forum in Karpacz and is expected to be featured again at the Pomeranian Intermodal Transport Congress in Gda?sk later in October. Both events highlight Poland’s growing commitment to advancing hydrogen-based transportation solutions.
As Hydrogen Central pointed out, the hydrogen train will likely attract eco-conscious tourists, offering a quieter, cleaner, and more efficient way to experience the natural beauty of Western Poland. Unlike traditional diesel locomotives, hydrogen-powered trains reduce fuel and maintenance costs, operate with less noise, and pose no risks to respiratory health.
Beyond environmental benefits, the SM42-6Dn symbolizes a broader shift toward sustainable tourism and green mobility. In a warming world, where communities increasingly feel the pressure of climate change, initiatives like this represent both technological innovation and social responsibility. Cleaner air, quieter travel, and reduced energy consumption translate into healthier lifestyles and preserved natural landscapes, crucial elements for long-term sustainability.
“This innovation positions Poland as a leader in sustainable rail transport in Central Europe, following in the footsteps of countries like Germany, which has also embraced hydrogen-powered trains,” concluded Hydrogen Central. “For travelers and policymakers alike, the SM42-6Dn serves as a model for balancing environmental responsibility with operational efficiency.”
