Alstom delivered the first Traxx Passenger electric locomotive for Romania’s Railway Reform Authority (ARF), marking the start of a 16-unit programme aimed at renewing the country’s passenger fleet, according to Railway Gazette.
ARF, the Romanian Transport Ministry’s body for implementing passenger rail policy, confirmed that the first unit, designated ARF002, was delivered on 7 April at Alstom’s depot within the CFR Grivița workshops in Bucharest. The four-axle locomotive, capable of running at speeds of up to 200 km/h, is equipped with fully suspended traction motors and is capable of hauling up to 16 passenger coaches, with the unit also fitted with onboard ERTMS.
Before entering passenger service, ARF will first have to run endurance testing on the Alstom train, which includes 10,000 km of operation before the locomotive is cleared for commercial use. With those tests set to begin in the coming weeks alongside driver training, the locomotives will ultimately be operated by state passenger operator CFR Călători under Romania’s public service contracts.
Routes and deployment
ARF has indicated that the Alstom locomotives will be deployed across several of Romania’s main electrified corridors, including:
- Dej–Brașov–Bucharest–Constanța — linking Dej in northern Romania with Brașov in the centre of the country, Bucharest in the south-east, and Constanța on the Black Sea coast.
- Timișoara–Arad–Brașov–Bucharest–Constanța — running from western Romania, near the Hungarian border, through central Romania to Bucharest and onward to the Black Sea port of Constanța.
- Timișoara–Cluj-Napoca–Iași — connecting western Romania with Cluj-Napoca in the north-west and Iași in the north-east, near the border with Moldova.
- Iași/Suceava–Bucharest–Constanța — linking two major cities in north-eastern Romania to Bucharest and then to Constanța on the country’s south-eastern coast.
Funding shift to Modernisation Fund
The project was initially backed by financing under Romania’s Recovery and Resilience Plan (PNRR), including coverage for long-term maintenance. ARF now says funding will instead be provided in full through the EU Modernisation Fund, with the financing contract expected to be signed in the coming period.
As countries worldwide race to decarbonise their transport networks, the global rail sector has emerged as a critical battleground. At the forefront of this shift is the French multinational Alstom, whose state-of-the-art Electric Multiple Units (EMUs) have become the gold standard for high-performance, sustainable mobility. From regional corridors to ultra-high-speed networks, Alstom’s electric fleet is rewriting the rules of modern transit.
By moving away from traditional diesel propulsion and heavily investing in next-generation traction systems, predictive digital maintenance, and aerodynamic architecture, Alstom is actively supporting the European Green Deal and similar international climate initiatives.
The Technological Edge: Efficiency and Modularity
What sets Alstom’s modern electric trains apart is their modular engineering platform. Instead of designing individual trains from scratch for every specific regional market, the company utilises highly adaptable families of trains—most notably the Coradia and Avelia platforms.
These fleets are engineered with lightweight aluminium bodyshells, regenerative braking systems that feed energy back into the overhead catenary lines during deceleration, and roof-mounted traction components that free up interior space for passenger comfort. Furthermore, Alstom’s recent push into digital signalling solutions, such as the European Train Control System (ETCS), ensures maximum safety and higher frequency on existing tracks.
Global Impact: The Modernisation of Regional Networks
The real-world impact of Alstom’s rolling stock expansion is visible across diverse geographies. Central and Eastern Europe, for instance, has heavily relied on these acquisitions to modernise aging train fleets.
Beyond Catenaries: BEMU and Hybrid Innovation
While overhead electric wires are the most efficient way to power heavy rail, electrifying thousands of kilometres of rural tracks is often cost-prohibitive. To solve this, Alstom has developed Battery Electric Multiple Units (BEMUs).
These hybrid trains operate seamlessly under standard electric wires where available, while charging their onboard lithium-ion batteries. When the train reaches a non-electrified segment, it automatically switches to battery power, ensuring a continuous, emission-free journey without requiring the costly deployment of new physical infrastructure.
The Road Ahead
As urbanisation accelerates and the demand for climate-conscious travel grows, the role of electric rail becomes undeniable. For Alstom, the challenges of the late 2020s involve managing global supply chain dynamics and scaling up production to meet a historic backlog of green transport orders. Through data transparency, aerodynamic industrial design, and an unwavering commitment to engineering excellence, Alstom’s electric fleet continues to run smoothly toward a zero-emission future.
