Croatia Accelerates Rail Modernisation: Rijeka–Zagreb Corridor Upgrade

Croatia has embarked on an ambitious modernisation of its Rijeka–Zagreb railway, a strategic corridor linking the Adriatic port city of Rijeka with the nation’s capital. The project focuses on track doubling and electrification, which will significantly increase the line’s capacity for both freight and passenger services. As one of Croatia’s busiest transport arteries, this corridor serves as a vital gateway for international trade, connecting Adriatic shipping routes with inland European markets. By expanding and modernising the infrastructure, Croatian authorities aim to streamline freight operations, reduce transit times, and improve reliability. The upgrades will not only accommodate heavier freight volumes but also ensure that passenger trains can run more frequently and punctually, enhancing regional mobility and convenience.

Track doubling is a cornerstone of the initiative, allowing simultaneous two-way traffic on previously single-track sections. This improvement will eliminate bottlenecks, a critical factor for freight logistics and time-sensitive cargo shipments destined for Europe’s heartland. Electrification, meanwhile, aligns with Croatia’s commitment to sustainable transport, reducing dependence on diesel locomotives and lowering carbon emissions. The combination of these upgrades is expected to transform the Rijeka–Zagreb corridor into a modern, efficient, and environmentally friendly railway link. Stakeholders, including logistics companies and passenger operators, anticipate improved operational flexibility, which could translate into economic gains for Croatia by enhancing the competitiveness of its ports and rail transport sector.

Beyond technical upgrades, the project promises broader regional benefits. Improved rail connectivity will facilitate international passenger travel, linking Croatia more seamlessly with neighboring countries and broader European rail networks. For freight, the enhanced corridor supports smoother, faster flows of goods between the Adriatic coast and Central Europe, reinforcing Croatia’s strategic role in regional trade. Investments in signalling, safety systems, and station infrastructure are integral to the modernisation, ensuring that the upgraded line meets contemporary operational standards. As the Rijeka–Zagreb railway enters this next phase of development, Croatia positions itself as a forward-looking player in European rail transport, combining efficiency, sustainability, and regional integration to strengthen both economic and passenger rail services.
