Your EU – Your projects in Hungary: speeding up sustainable transport

Sustainable transport is central to Europe's efforts to cut emissions, reduce congestion and ensure reliable connections for people and businesses. The EU supports infrastructure upgrades, innovation and cross-border cooperation so that mobility becomes safer, cleaner and more inclusive.

Hungary's central location makes it a key transport hub, but bottlenecks and capacity constraints, particularly around the capital, Budapest, present an ongoing challenge. Through major investments in modern infrastructure and innovative mobility solutions, including projects managed by CINEA, the EU is helping Hungary move towards a more sustainable transport future.

Below we explore three EU-supported initiatives that illustrate how ambition is being turned into reality.

Kelenföld - Százhalombatta-Pusztaszabolcs railway upgrade: removing bottlenecks

With almost €370 million from the EU's Connecting Europe Facility (CEF Transport), nearly 50 km of double-track railway on the Kelenföld - Százhalombatta-Pusztaszabolcs section has been modernised. The works included full track reconstruction and the deployment of trackside ERTMS (European Rail Traffic Management System).

As part of the wider Budapest-Kelenföld-Croatian border corridor upgrade, this project removed a major bottleneck along the Mediterranean Core Network Corridor - an EU priority route linking Spain to Hungary and a vital east-west route for freight and passenger traffic.

This has resulted in increased capacity and supported a shift from road to rail, while contributing to regional and national economic development. The modernised line improves safety, efficiency, reliability and quality of rail services.

UPPER: strengthening cooperation to modernise public transport

Public transport is essential for sustainable urban mobility. Backed by €20 million from the Horizon Europe research programme, the UPPER project helps cities and regions make public transport more attractive and user-friendly. Budapest's public transport authority (BKK) is one of the partners.

Within UPPER , Budapest is enhancing its BudapestGO journey planner with predictive travel planning in direct response to customer requests. This will also generate data to inform the future design of integrated multimodal mobility services. To improve reliability, the city is rethinking public transport prioritisation, including enhanced bus and tram priority lanes and updated traffic-light programmes.

"UPPER is helping cities and regions learn from one another and adopt solutions that can be scaled across Europe. Measures now being tested by BKK can make public transport an even more competitive and attractive option, not only in Budapest but across Europe," explains Mircea Steriu, UITP, UPPER Coordinator.

STARGATE: greening airport operations in Budapest

Aviation also plays a key role in Europe's mobility system, and airports are under increasing pressure to reduce emissions and boost operational efficiency. Budapest International Airport participates in the EU-funded STARGATE project - led by Brussels Airport - which tests practical solutions for cleaner and smarter airport operations. The project's results are shared widely so other airports can benefit from the same approaches.

In Budapest, one of the activities underway is the development of an airport-specific navigation app. It will provide precise route planning for service vehicles and improve situational awareness on aircraft movement areas. Covering the airport's complex 1,500-hectare layout, the tool will enhance safety for up to 1,000 users and is set to launch in 2026.

"As a 'fellow airport', we are drawing inspiration from the digital tools and innovations being tested as part of the STARGATE project. The solutions will allow Budapest Airport to become more competitive and sustainable, supporting our decarbonisation goals," said Sarolta Katona, Head of Sustainability, Budapest Airport.

Cleaner, more resilient and better connected

Together, these projects - from major rail upgrades and smarter public transport to greener, digitally enhanced airport operations - show how EU support is helping Hungary build a transport system that is cleaner, more resilient and better connected for everyone.

Your EU - Your projects: where EU support makes a difference

These examples show how EU programmes managed by CINEA translate European ambitions into concrete results and impact. By combining funding with expert advice and cross-border cooperation, the EU helps innovative projects scale up, deliver benefits for citizens and businesses, and support a more sustainable, resilient Europe.
