The new model is based on the proven design of the diesel railbus Regio-Shuttle RS1, which has been successfully operated in Germany and the Czech Republic for nearly three decades.

First Hydrogen Train in the USA Set to Launch in 2024

The RS ZERO was first unveiled in August 2024, featuring a modern drive system that produces no harmful emissions, making it an environmentally friendly alternative to traditional diesel trains.

During InnoTrans, Stadler signed an agreement with the Thuringian authorities and the operator Erfurter Bahn to launch a pilot project for the operation of the RS ZERO with a hydrogen engine.

Passenger trial runs are planned for mid-2026, marking a significant step in the development of sustainable transport in the region.

The RS ZERO can be configured as a single or double-car unit, depending on needs.

The single-car version offers 59 or 75 seats depending on the presence of a toilet, while the double-car version provides between 148 and 165 seats.

The interior design features a low-floor area, easy access for all passenger categories, a door width of 1300 mm, and comfortable travel conditions.

The technical specifications of the RS ZERO are also impressive.

The maximum speed reaches 120 km/h, the power output of the single and double-car versions is 600 and 1200 kW respectively, and the tractive effort during acceleration reaches 70 and 140 kN.

The railbus demonstrates excellent axle load and acceleration performance, ensuring high efficiency and dynamic operation.

Additionally, Stadler is developing a modification of the RS ZERO that operates on overhead lines and batteries, expanding the application possibilities of this railbus in various operating conditions.

This model promises to become an important part of sustainable transport in the future, offering comfort and eco-friendliness at new levels.
