en.Wedoany.com Reported - On June 12, 2026, Petra Berg, Minister for Environment, Climate, Transport and Consumer Protection of Saarland, together with Stadler Rail Germany and DB Regio, unveiled the new Stadler Flirt Akku battery-powered trains at Saarbrücken Central Station. The fleet consists of 44 two-car battery multiple units (BMUs), which will replace diesel traction on all regional lines except cross-border routes to France. Five trains are currently being tested, and approximately 300 drivers are undergoing type training in preparation for phased deployment starting in October 2026.
This project converts the entire regional rail network of Saarland (excluding lines jointly operated with SNCF in France) to battery-electric operation. Trial operations begin in October 2026 on the Saarbrücken–Zweibrücken–Pirmasens (RB 68) and Neustadt–Landau–Karlsruhe (RE 6/RB 51) lines, followed by expansion in November 2026 to the Dillingen–Niedaltdorf (RB 77) and Kaiserslautern–Pirmasens (RB 64) lines. In December 2026, all services in the Niedtal region will enter full commercial operation. Additional lines—Kaiserslautern–Lauterecken–Grumbach (RB 66), Kusel (RB 67), Landau–Pirmasens (RB 55), and Wenden–Bad Bergzabern (RB 54)—will be converted by 2029. Upon completion, DB Regio will operate 44 Flirt Akku trains on the network, electrifying the entire fleet, including BMUs on the SÜWEX and E‑Netz Saar RB networks.
Saarland's plan reflects a growing trend among German states to adopt battery-powered regional trains for decarbonizing partially electrified lines. The first large-scale order for Stadler's Flirt Akku platform came from the Schleswig-Holstein Local Transport Association (NAH.SH), which signed a contract in 2019 for 55 two-car units totaling approximately €600 million (source: Stadler, 2019), with these trains entering service in 2023. Saarland's order of 44 units represents a similarly sized fleet, though financial details were not disclosed at the launch. Other German networks, such as the Palatinate battery train project and Bavaria's ORION network, are also moving toward battery operation, reinforcing a nationwide shift away from diesel regional rail vehicles.
The phased deployment through 2029 provides time for DB Regio to integrate personnel training, charging infrastructure, and energy supply. Except for cross-border services to France, which retain diesel multiple units, the state will establish a predominantly electric regional fleet, aligning with Germany's broader high-speed rail investment strategy (source: Market Analysis, 2025) targeting climate-neutral transport. The undisclosed project costs may face scrutiny, especially amid public budget reviews, particularly when similar orders have shown price tags in the hundreds of millions of euros.
Q: Which lines in Saarland will first deploy battery-powered passenger trains?
A: Trial operations begin in October 2026 on the Saarbrücken–Zweibrücken–Pirmasens (RB 68) and Neustadt–Landau–Karlsruhe (RE 6/RB 51) lines, followed by the Dillingen–Niedaltdorf (RB 77) line in November 2026.
Q: How many battery trains will DB Regio ultimately operate in Saarland?
A: Once all conversion phases are complete, DB Regio will operate 44 two-car Stadler Flirt Akku trains on the network, fully electrifying the regional fleet (excluding French lines jointly operated with SNCF).
Q: What is the total cost of the Saarland battery train project?
A: No financial figures were officially disclosed by the Saarland Ministry of Transport or DB Regio at the launch. No independent cost estimates have been published.
