EUROPE: Leasing company Akiem has become the launch customer for an electric-battery bi-mode version of Siemens Mobility’s Vectron locomotive, which will be able to operate using overhead electrification where available and battery power on non-electrified sections of route.
The modular traction system can be offered with flexible configurations of up to more than 2 MWh, delivering up to 2 400 kW to the wheels in both battery mode and when operating under AC overhead. The locos with a weight of approximately 90 tonnes will be configured to run at up to 160 km/h, with a maximum tractive effort of 300 kN; they will also be able to provide a train supply power of 480 kVA.
The signing of a framework agreement for 80 locomotives with a firm order for 50 for delivery from 2029-30 ‘is a strong vote of confidence in our technology’, said Andre Rodenbeck, CEO Rolling Stock at Siemens Mobility, on March 24. ‘With the Vectron Dual Mode Electric/Battery, we are taking a major development step based on the proven Vectron platform, adding a new fully electric member to the Vectron family. For customers, this means greater operational flexibility on routes where electrification is not continuous, while supporting the transition to more sustainable rail operations.’
Akiem had previously ordered a total of 120 Vectron and Vectron Dual Mode locomotives since 2021. CEO Fabien Rochefort said Akiem and Siemens Mobility shared ‘a common vision that Vectron Dual Mode Electric/Battery will meet the vast majority of our customer needs when operating on non-electrified lines, significantly reducing costs of operations against existing market solutions, while reducing CO2 emission and noise.’
A Vectron AC electric locomotive with a battery module suitable for last-mile and shunting operation was unveiled at the Transport Logistic trade fair in München in 2025. Widmer Rail Services company JeMyn has ordered two for delivery in 2027, with type approval initially to be obtained for Germany, Austria and Switzerland.
