Siemens and Akiem Agree Deal for 80 New Battery-Ready Vectron Locomotives

Siemens Mobility has secured a major framework agreement with rolling stock leasing company Akiem for up to 80 Vectron locomotives, alongside unveiling a new electric and battery-powered variant of its popular platform.

The initial order covers 50 locomotives, with deliveries expected to begin in 2029 and continue into 2030. The agreement also includes an option for a further 30 units.

The deal coincides with the introduction of a new dual-mode electric/battery Vectron locomotive, expanding the existing range. Unlike previous dual-mode versions that combine electric and diesel power, this latest model replaces the diesel engine with onboard batteries, enabling operation both under overhead wires and on non-electrified routes.

The new design builds on Siemens’ established Vectron Dual-Mode platform but incorporates a modular battery system. This setup allows flexible energy storage configurations of more than 2 MWh and delivers up to 2,400 kW of power in both electric and battery modes.

Other key specifications include a top speed of 160 km/h, a tractive effort of up to 300 kN, a weight of around 90 tonnes, and onboard train supply power of 480 kVA.

This is not the first collaboration between the two companies. Since 2021, Akiem has already placed orders for 120 Vectron and Vectron Dual-Mode locomotives, highlighting an ongoing partnership.

Akiem CEO Fabien Rochefort said the new battery-equipped locomotives are expected to meet the majority of operational requirements on non-electrified lines, while lowering operating costs compared with existing alternatives. He also noted the benefits in reducing emissions and noise.

Earlier this year, Siemens Mobility also received approval for its Vectron Dual Mode locomotives to operate across the Germany–Austria border, further demonstrating the platform’s versatility.

André Rodenbeck, CEO of Rolling Stock at Siemens Mobility, described Akiem’s order as a strong endorsement of the technology. He said the new battery-electric version represents a significant step forward, offering operators greater flexibility on partially electrified routes while supporting the shift toward more sustainable rail transport.
