The Future of Railway


The European Union Railway Agency (ERA) has recently released its Rolling Stock Fleet Study, offering a comprehensive analysis of Europe’s rail fleet.

Drawing on ERA registers, open sources, and industry data, the report provides critical insights into the size and characteristics of the fleet, supporting innovation and operational improvements across the sector.

The study identifies approximately 835,000 registered vehicles as of mid-2024, including

  • 130,000 traction vehicles

  • 635,000 wagons

  • 45,000 coaches and

  • 18,000 special vehicles.

This data fills key knowledge gaps and informs strategies to meet Europe’s goal of doubling rail freight and tripling high-speed passenger transport by 2050.

Filling the Gaps 
ERA’s Analysis of Europe’s Rail Fleet and Future Needs

ERA uses three registers -- European Vehicle Register (EVR), European Register of Authorised Types of Vehicles (ERATV), and Vehicle Keeper Marking (VKM) register -- to manage rail vehicle data. However, gaps in data quality, incomplete coverage (only 23% of vehicles have an ERATV type ID), and limited analytical design hinder interoperability analysis and innovation projects like Digital Automatic Coupling (DAC) and European Rail Traffic Management System (ERTMS).

To address this, ERA conducted a study to enrich datasets, analyse fleet characteristics, and identify future needs. The findings aim to improve data quality and support a more interoperable and innovative EU rail system.

Key Findings

  • Silent Wagons: European Vehicle Register (EVR) data doesn’t fully cover silent wagons; many wagons have been upgraded with silent brakes.

  • Agricultural Wagons: Data on grain wagons varies; more operational research is needed.

  • Intermodal Wagons: 105,000 intermodal wagons were identified, but we need to clarify how many are actually used for this purpose.

  • Power Systems: Current power system data is inconsistent; classification needs updating.

  • Electrification: Multi-system vehicles, capable of running on different electrification types, are common.

  • Tractive Effort: Data on 40,000 vehicles was gathered, but its use for statistics is debatable.

  • Trainsets: About 13,100 trainsets were identified through EVN data.

  • Seating Capacity: Focus should shift from trainset-level seating to individual cars.

  • ETCS: Incomplete data on the European Train Control System (ETCS); more details needed by linking with specific vehicle identifiers.

  • Vehicle Keepers: More wagons are now owned by lessors than operators.

  • Rolling Stock Needs: Initial data suggests further analysis is needed to estimate future needs by 2050.

  • Key Observations
    The study reveals critical insights and challenges in analysing EU rail fleet data:

  • Open-Source Data: Significant vehicle data is publicly available, despite restrictions under the European Vehicle Register (EVR) Decision[DD1] . Parallel registers also exist, but data governance remains inconsistent.

  • Enhanced Insights: Custom scripts unlocked ERA register data, creating enriched datasets to support policy and retrofitting projects like DAC and ETCS. The study also identified areas for improving data quality.

  • Data Limitations: Open-Source data [DD2] is incomplete, time-consuming processing, and lacks signalling information. Rail data lags behind aviation and maritime sectors, where open platforms like Flightradar24 and MarineTraffic provide integrated insights.

  • Future Solutions: Linking EVN to ERATV IDs will improve data for new vehicles. For legacy fleets, alternative methods are needed to close gaps.

  • Sectoral Lessons: Better data availability and integration, as seen in other transport sectors, could drive innovation and enhance rail system interoperability.

ERA Proposals

The study recommends that ERA improve technical data for vehicles lacking ERATV IDs, use enriched datasets for better impact assessments, and enhance data quality in registers. It also suggests streamlining EVR restriction code updates, refining ERA’s Railway Factsheets, and correcting EVN-based errors for the statistical office of the European Union (EUROSTAT).

By addressing these data gaps and enhancing interoperability, ERA’s study lays the foundation for a more connected, efficient, and sustainable European rail network, supporting the sector’s ambitious growth targets for 2050.

EU Fund
€350 Million EU-Funded Rail Project Boosts Croatia-Hungary Connectivity

Croatia has partially opened a €350 million rail upgrade, co-funded by the EU, to boost freight and passenger connectivity with Hungary.

The project includes a 15-kilometre dual-track section between Koprivnica (Croatia) and Gyékényes (Hungary), as well as a new Drava River bridge. Expected to be completed by the end of 2025, the upgrade will improve cross-border transportation and reduce bottlenecks.

The railway section, part of the "Križevci–Koprivnica–State Border" project, features a double-track bridge over the Drava River and upgraded signaling systems.

Once finished, the line will support speeds up to 160 km/h and handle 30 freight trains daily—markedly increasing traffic from the Port of Rijeka to Hungary. The project is 75% complete, with work continuing on the section between Mučna Reka and Koprivnica.

The new 300-meter Drava Bridge, constructed using a unique longitudinal push technique, replaces a single-track bridge and increases capacity for modern freight.

The project is part of HŽ Infrastruktura’s €6 billion rail modernization plan, aimed at enhancing key corridors like Rijeka-Zagreb-Budapest and Slovenia-Zagreb-Serbia to support economic growth and regional trade.
