Battery-Electric Dual-Mode Locomotives Expand Rail Decarbonization

Siemens Mobility and Akiem have signed a framework agreement for up to 80 Vectron locomotives, including a firm order for 50 units. The agreement introduces a new dual-mode electric/battery locomotive designed to operate under overhead lines and on non-electrified routes, supporting rail decarbonization and operational flexibility.

Expanding the Vectron Platform
The new locomotive builds on the existing Vectron Dual Mode platform, replacing the diesel engine with a modular traction battery system. This enables operation both under AC overhead line power and in battery mode on sections without electrification.

The platform is designed for freight and passenger applications where full network electrification is not available, allowing continuous operation without reliance on fossil fuels.

Technical Characteristics and Performance
The dual-mode electric/battery locomotive is engineered to deliver comparable performance across operating modes. It supports battery configurations exceeding 2 MWh and provides traction power of up to 2,400 kW both under catenary and in battery operation.

Additional specifications include a maximum speed of 160 km/h, tractive effort of up to 300 kN, and a total weight of approximately 90 tonnes. The locomotive also provides train supply power of 480 kVA, enabling compatibility with passenger services.

These characteristics position the platform for mixed-traffic use, including freight corridors and regional passenger operations.

Deployment Timeline and Leasing Model
Deliveries are scheduled to begin between 2029 and 2030. As launch customer, Akiem will integrate the locomotives into its leasing portfolio, making the technology accessible to multiple operators across Europe.

This leasing model enables faster adoption of new traction technologies without requiring operators to make large upfront capital investments.

Supporting Rail Decarbonization
Battery-based dual-mode locomotives address a key challenge in rail transport: the presence of partially electrified networks. By enabling zero-emission operation on non-electrified sections, the platform reduces dependence on diesel traction.

This approach supports the transition toward low-emission rail transport while maintaining operational continuity across existing infrastructure.

Position Within Alternative Traction Technologies
The new Vectron variant complements Siemens Mobility’s broader portfolio of alternative traction systems, including battery-electric and hydrogen-powered regional trains. These technologies provide multiple pathways for reducing emissions depending on route characteristics and infrastructure availability.
