Stadler manifests market leadership in alternative drive technologies: DB Regio orders more battery-operated trains

Electric instead of diesel: DB Regio orders trains of the type FLIRT Akku from Stadler again. 14 trains will also be used in the north-east of Germany. Stadler is expanding its market leadership considerably in the field of alternative drives in Germany with this third supply contract for battery-operated vehicles. Stadler will be delivering at least 113 vehicles with alternative drive technologies over the next five years. The two-part vehicles for Mecklenburg-Vorpommern will go into passenger service from December 2026.

Starting at the end of 2026, Deutsche Bahn will use the innovative battery-operated vehicles from Stadler on a route that was previously serviced by diesel-operated vehicles in the so-called H-network in Mecklenburg-Vorpommern. The «H-network» stands for «The use of electrical battery-hybrid vehicles». This means that these routes can be serviced locally and completely emission-free – without having to install catenaries throughout the entire network.

The two-part vehicles of the type FLIRT Akku will be used for typical transport period of 13 years, and are tailored to the needs of the network that runs along part of the Baltic Sea coast. The H-network Warnow has a service scope of 1.5 million train kilometres a year and covers the routes of the RB11 between Wismar – Rostock – Tessin and the RB12 between Bad Doberan – Rostock – Graal-Müritz.

The FLIRT Akkus provide space on 99 seats. Two spacious and accessible multi-purpose areas are provided for wheelchairs, pushchairs and bicycles. The air-conditioned and step-free vehicles also have a wheelchair-accessible toilet. All trains are equipped with WLAN, power sockets as well as video surveillance of the passenger areas and a modern passenger information system and ensure contemporary ride comfort.

“With this new order for battery-operated vehicles from the Deutsche Bahn, we have further consolidated our market leadership in the field of alternative drives. Since 2019, Stadler has sold 113 vehicles with alternative drive technologies in Germany. It makes us very proud that our FLIRT Akku not only makes an ecological and innovative contribution to climate-friendly traffic policies, but also significantly boosts efficiency. If we consider the average life of a rail vehicle of around 30 years, battery-operated vehicles are more cost-effective than diesel-operated trains”, said Jure Mikolčić, CEO of Stadler in Germany.

“With the battery–electric multiple units, which will replace diesel vehicles, we are taking an important step towards climate neutrality with the state. As DB Regio, we are proud to put the first environmentally friendly network of this type into operation in Mecklenburg–Western Pomerania.” Carsten Moll, Chairman of DB Regio Northeast

FLIRT Akku: The world record train
The FLIRT Akku is the battery–operated version of the FLIRT type series by Stadler. The vehicle is highly versatile thanks to that fact that it is designed for non–electrified and partially electrified tracks. The operational reach of the vehicle is about 100 km, which means that 80 percent of the non–electrified routes in Germany can be used by regional trains in battery mode. With 224 driven kilometres in pure battery mode, the FLIRT Akku holds the world record for the longest journey by a regional train in pure battery mode without additional charging.

The FLIRT AKKU is a single–storey, easily customised regional train. Its vehicle concept is largely based on the already approved and tested electrical trains FLIRT for exclusive operation under a catenary. Most of the traction equipment and the most important mechanical components have been retained. All FLIRT models have a lightweight aluminium frame. Maintenance–friendly designs and components that have proven themselves thousands of times over help to keep operating, energy and servicing costs to a minimum. Two to four–part train compositions can be realised in the battery–operated variant. Like the FLIRT, the FLIRT Akku can also be customized highly flexibly with respect to the number of seats, passenger flow or interior design.

The FLIRT by Stadler is a single–storey train for local and long–haul transport. To date, Stadler has sold more than 2000 of this best–selling model in 20 countries. In addition to purely electrical, diesel or mixed drives, Stadler also supplies the FLIRT with alternative drives such as batteries and hydrogen. For instance, Stadler developed the first FLIRT with a hydrogen drive for the American San Bernardino County Transportation Authority (SBCTA).
