Stadler, a rail vehicle manufacturer, has introduced the RS ZERO, a revolutionary model that combines hydrogen and battery drives to enable emission-free operation. The RS ZERO, as the successor to the Regio-Shuttle RS1, offers both hydrogen and battery power options, aiming to provide eco-friendly solutions in rail transportation. With around 500 RS1 units operating in Germany and the Czech Republic, Stadler enhances the legacy of the Regio-Shuttle by incorporating advanced, sustainable drive systems in the RS ZERO. The RS ZERO targets the need for CO2 emission-free operation on non-electrified railway lines, which constitute a significant portion of rail infrastructure in Germany and Europe. By offering a lightweight design and adaptable features for different rail networks, the RS ZERO proves to be a cost-effective solution for secondary routes with lower traffic. The vehicle prioritizes passenger comfort and accessibility, with barrier-free access, ample seating options for up to 150 passengers, and provisions for bicycles, pushchairs, and luggage storage. Stadler's CEO and Executive Vice President emphasize the company's focus on creating a lightweight vehicle for emission-free operation on secondary routes, contributing to a sustainable future in rail transport. The RS ZERO represents Stadler's commitment to innovation and technology leadership in the rail industry, aiming to lead transport companies towards a CO2-neutral future with its sustainable and eco-friendly solution for local passenger travel. By introducing the RS ZERO, Stadler is setting new benchmarks in environmentally friendly rail transport and addressing the challenges posed by non-electrified railway lines.
