Lokaltog has selected Stadler, together with Furrer+Frey, to supply four RS ZERO battery trains and their charging infrastructure for the Nærumbanen, the 7.8 km line linking Jægersborg and Nærum north of Copenhagen. It is the first commercial award in Europe for the platform, which was unveiled in 2024.
The RS ZEROs will replace the four diesel RegioSprinters built in 1999. Entry into service is planned for the first half of 2031, once the regional councils approve the purchase and the contract, expected to be signed in early 2027, is concluded.
Technology and charging
Derived from the Regio-Shuttle RS1, of which Stadler has sold almost 500 units, the RS ZERO incorporates proven components from its electric and battery projects. The Berlin-Pankow plant will build the vehicles.
Thanks to their batteries, the trains will be able to operate on electric traction throughout the line, which has no overhead electrification. Swiss company Furrer+Frey will supply the charging and power supply systems.
Expected impact
Lokaltog estimates annual savings of around 800 tonnes of CO2 compared with the current diesel operation, as well as reduced noise and vibration. The company has already ordered 24 FLIRT Akku units for other lines, which will enter service between 2028 and 2029.
