Siemens Vectron Dual Mode Gains German-Austrian Cross-Border Approval, Boosting European Rail Interoperability

MUNICH, GERMANY – Siemens Mobility has achieved a significant milestone for European rail freight, securing authorisation for its Vectron Dual Mode locomotive to operate across the German-Austrian border. This approval makes Austria the second country after Germany to certify the versatile locomotive, with the first two units immediately handed over to Austrian operator Stern & Hafferl Verkehr to enhance sustainable cross-border logistics.

The authorisation, announced on January 14, 2026, marks a pivotal step in creating a more seamless and efficient rail network in Central Europe. The approval enables the Vectron Dual Mode to run uninterrupted services between Germany and Austria, eliminating time-consuming and costly locomotive changes at the border or on routes with intermittent electrification. Stern & Hafferl Verkehr, an established Austrian rail company, will receive a total of six of these locomotives, deploying them for last-mile freight operations and contributing to a more environmentally conscious transport chain.

At the heart of the locomotive’s cross-border capability is the modular Siemens On-board Unit Trainguard Basic, equipped with the European Train Control System (ETCS) Baseline 3.6. This advanced system ensures safe and interoperable operation across diverse national signalling protocols. Technically, the 90-ton locomotive operates on a standard 1,435 mm track gauge and delivers a maximum output of 2,400 kW (2.4 MW) when running on 15 kV AC overhead catenary. On non-electrified sections, its powerful diesel engine provides 2,000 kW (2.0 MW) of traction power, fed by a 2,600-litre fuel tank, all while capable of reaching a top speed of 160 km/h. A variant supporting both 15 kV and 25 kV AC systems is also available, further expanding its potential operating range across Europe.

The introduction of dual-mode technology addresses a critical challenge in the rail industry’s push for sustainability and efficiency. While major corridors are electrified, many “last mile” connections to ports, industrial sites, and regional depots remain non-electrified. This development from Siemens offers a pragmatic solution that competes with other emerging green technologies. For instance, in North America, public transport authorities like New York’s MTA are investing heavily in different solutions, such as a recent $386 million order for diesel-battery hybrid locomotives from Wabtec subsidiary MotivePower. Siemens’ diesel-electric approach provides a proven, robust alternative for freight operators looking to decarbonise without requiring new battery charging infrastructure.

Key Takeaways

• Enhanced Interoperability: Austria becomes the second country to approve the Vectron Dual Mode, enabling seamless freight and passenger traffic with Germany without locomotive changes.
• Increased Efficiency: The dual-mode capability allows for continuous journeys across electrified main lines and non-electrified “last mile” tracks, boosting logistical efficiency and supporting the modal shift from road to rail.
• Advanced Technology: Equipped with ETCS Baseline 3.6, the locomotives are prepared for modern, digitally controlled European rail networks, ensuring high safety standards.

Editor’s Analysis

This authorisation is more than just a technical approval; it’s a strategic enabler for the European Green Deal’s transport objectives. The Vectron Dual Mode directly tackles the Achilles’ heel of rail freight: the fragmented nature of electrification. By providing a single-locomotive solution for end-to-end journeys, Siemens is lowering the operational barrier for shippers to choose rail over road. This pragmatic “bridge” technology offers immediate CO2 reductions by maximising electric operation where available, while retaining the flexibility of diesel for full network access. As the industry moves towards future technologies like hydrogen and battery power, the Vectron Dual Mode serves as a critical, market-ready tool that delivers tangible environmental and economic benefits today, strengthening rail’s competitive position in the European logistics market.

Frequently Asked Questions

What is a dual-mode locomotive?

A dual-mode locomotive is a railway vehicle that can draw power from two different sources. The Siemens Vectron Dual Mode combines an electric powertrain, which uses power from overhead lines (catenary), with an onboard diesel engine for operation on non-electrified track sections.

Why is cross-border authorisation for Germany and Austria significant?

This authorisation is significant because it allows a single locomotive to operate seamlessly between the two countries, which form a major European freight corridor. It eliminates delays and costs associated with changing locomotives at the border, thereby increasing the speed and reliability of international rail transport.

Which company is the first Austrian operator of this specific locomotive?

The first Austrian rail operator to receive and deploy the Vectron Dual Mode with German-Austrian authorisation is Stern & Hafferl Verkehr. The company has taken delivery of the first two of a total order of six locomotives.
