In a first, rail vehicle combines hydrogen, battery power for emission-free ops

The RS ZERO combines hydrogen and battery power for emission-free operation.
The new model, which is a successor to the Regio-Shuttle RS1, offers a choice between two eco-friendly drive technologies: hydrogen and battery power.
So far, the Regio-Shuttle has been one of the most popular vehicles in German regional rail transport for 28 years, with around 500 RS1 units in operation across Germany and the Czech Republic.
Stadler is now enhancing this reliable technology by incorporating advanced, eco-friendly drive systems. The RS ZERO will aim to set standards for environmentally friendly rail transport and introducing a unique feature in the industry, the company says .
CO2 emission-free solution for non-electrified railway lines
In Germany, 38% of railway lines are not electrified, and the figure rises to 43% across Europe. To boost rail traffic as part of the transport transition, many old and non-electrified lines need to be revived. The RS ZERO, with its battery and hydrogen drives, provides a solution for CO2 emission-free operation on these routes.
The Swiss manufacturer is also advancing the RS1’s legacy while addressing current challenges with these new sustainable powertrains. The RS ZERO maintains the RS1’s distinctive trapezoidal window strips but incorporates a modern LED wing.
“The Regio-Shuttle RS1 is an important part of Stadler’s history. We delivered the last vehicle to a customer 11 years ago. Now I am delighted that we start a new chapter in this success story with the RS ZERO which enables us to further expand our technological leadership in the field of alternative drive technologies,” said Peter Spuhler, Chairman of the Board of Directors of the Stadler Group.
Furthermore, each vehicle can be adjusted to suit the conditions of the rail network. With its lightweight design and axle load of under 18 tonnes, it is well-suited for cost-effective service on secondary routes with lower traffic.
According to Jure Mikolčić, CEO of Stadler Germany, the RS ZERO prototype represents the next step in alternative drive technology at their Berlin site, following the battery-electric FLIRT Akku.
Barrier-free access and ample seating for passengers
The RS ZERO comes in single and double units, seating between 70 and 150 passengers. It has a low entry height, a spacious low-floor area, and barrier-free access, making it easier for passengers with limited mobility.
Dr. Ansgar Brockmeyer, Executive Vice President of Marketing & Sales at Stadler Group, highlights that the goal was to create a lightweight vehicle for emission-free operation on secondary routes.
The additional features include spaces for bicycles, pushchairs, and bulky luggage, as well as lounge areas, standard and privacy seats, a wheelchair space, a WC, and a train office.
Furthermore, the company hopes that the RS ZERO will mark the beginning of a new era in regional rail transport, leading transport companies toward a CO2-neutral future with its sustainable solution for local passenger travel.
