Stadler Tests 44 Flirt Akku Trains in Saarland

Saarbrücken, Germany – Petra Berg, Saarland’s Minister of the Environment, Climate, Mobility, and Consumer Protection, alongside Stadler Rail Germany and DB Regio, introduced the new Stadler Flirt Akku battery-powered trains at Saarbrücken Central Station on 12 June 2026. The fleet will eventually number 44 two-car battery-electric multiple units (BMUs), replacing diesel traction on all regional lines except cross‑border services to France. Five trains are already present for testing, and approximately 300 drivers are undergoing type‑training ahead of phased roll‑out from October 2026.

What Is the Full Scope of This Project?

The project converts the entire Saarland regional rail network—excluding lines jointly operated with SNCF into France—to battery-electric operation. Trial passenger service starts on the Saarbrücken–Zweibrücken–Pirmasens (RB 68) and Neustadt–Landau–Karlsruhe (RE 6/RB 51) routes in October 2026, then extends to Dillingen–Niedaltdorf (RB 77) and Kaiserslautern–Pirmasens (RB 64) in November 2026. Full commercial operation on all Niedtal‑area services follows in December 2026. Further lines—Kaiserslautern‑Lauterecken‑Grumbach (RB 66), Kusel (RB 67), Landau‑Pirmasens (RB 55), and Winden‑Bad Bergzabern (RB 54)—will be converted by 2029. Once complete, DB Regio will operate 44 Flirt Akku trains on the network, making the entire fleet (including BMUs on the SÜWEX and E‑Netz Saar RB networks) electric.

Key Project Data

How Does This Compare to Similar Projects?

The Saarland programme mirrors a growing pattern of German states adopting battery‑electric regional trains to decarbonise partially electrified routes. Stadler’s Flirt Akku platform was first ordered at scale by the Schleswig‑Holstein local transport association (NAH.SH) in 2019, which signed a contract for 55 two‑car units with a total volume of approximately €600 million (Source: Stadler, 2019). Those trains entered revenue service in 2023. Saarland’s order of 44 units represents a comparable fleet size, though no financial details were released at the presentation. Other German networks, such as the Pfalz (Palatinate) battery‑train project and the ORION network in Bavaria, are also moving toward battery operation, reinforcing a nationwide trend away from diesel regional rolling stock.

Editor’s Analysis

The phased deployment in Saarland, stretching into 2029, gives DB Regio time to align crew training, charging infrastructure, and energy supply with the operational transition. By keeping diesel‑electric units only on cross‑border services to France, the state is creating a predominantly electric regional fleet that mirrors the drive toward climate‑neutral transport outlined in Germany’s broader high‑speed rail investment strategy for 2025 (Source: Market analysis, 2025). The absence of a disclosed project cost will likely be questioned as public budgets face scrutiny, particularly when comparable orders have shown price tags in the hundreds of millions of euros.

FAQ

Q: Which lines will see the first battery‑powered passenger trains in Saarland?
A: Trial passenger service begins in October 2026 on the Saarbrücken–Zweibrücken–Pirmasens (RB 68) and Neustadt–Landau–Karlsruhe (RE 6/RB 51) routes, followed by the Dillingen–Niedaltdorf (RB 77) line in November 2026.

Q: How many battery trains will DB Regio eventually operate in Saarland?
A: Once all conversion phases finish, DB Regio will run 44 two‑car Stadler Flirt Akku trains on the network, making the regional fleet fully electric except for joint services with SNCF to France.

Q: What is the total cost of the Saarland battery‑train project?
A: The financial volume was not officially disclosed by the Saarland Ministry or DB Regio at the presentation. No independent cost estimate has been published.
