Siemens Hydrogen Trains Romania Project Marks Shift to Zero Emission Rail
Siemens Mobility has been awarded a contract by Romania Railway Reform Authority to deliver Romania’s first hydrogen powered train fleet. The project includes 12 two car Mireo Plus H trainsets and a 15 year maintenance agreement, with operations expected to begin in 2029.
The trains use hydrogen fuel cell propulsion combined with battery storage, enabling zero local emissions and efficient energy use through regenerative braking. The design reduces weight, energy consumption and maintenance needs while using components already validated in earlier projects.
Each train will have a top speed of 120 km per hour and capacity for 131 fixed seats plus 5 folding seats. They can operate in multiple units for flexibility in service.
The fleet will include European safety systems such as ETCS and PZB, along with passenger information systems for real time updates. Maintenance will be carried out locally in Romania, supported by digital fleet management tools.
The project supports the replacement of diesel trains and contributes to reducing emissions and noise in regional rail transport.
