The vision of a Single European Railway Area—a seamless, borderless network where a passenger can travel from Lisbon to Warsaw or Stockholm to Rome with the ease of a single booking—is moving from an aspirational goal to a technical reality. The Community of European Railway and Infrastructure Companies (CER) has published its fifth progress report on the CER Ticketing Roadmap, an ambitious initiative launched in 2021 to redefine the passenger experience by 2025 and 2030. As the sector approaches critical deadlines, the momentum behind digital transformation and passenger protection highlights a pivotal moment for European rail.
Main Facts: The Roadmap to 2025 and Beyond
The CER Ticketing Roadmap serves as the industry’s strategic blueprint for simplifying the complex web of European rail distribution. By focusing on standardization and interoperability, the initiative seeks to eliminate the frictions that have historically hindered cross-border rail travel.
At its core, the roadmap is driven by two distinct phases. Phase one, concluding at the end of 2025, focuses on the digitalization of booking and ticketing systems, ensuring that disparate national rail networks can communicate effectively. Phase two, spanning from 2026 to 2030, shifts the focus toward a broader multimodal integration, incorporating rail into the wider European mobility ecosystem.
The fifth progress report, synthesized from biannual surveys conducted among passenger rail operators in November and December 2024, provides an candid assessment of the industry’s trajectory. While multilateral ticketing solutions are advancing, the report acknowledges that implementation remains a complex, ongoing process. Where bottlenecks or technical delays have surfaced, they are being managed through collaborative intervention between individual operators and the central project team, ensuring that the broader timeline remains intact.
A Chronological Perspective: The Evolution of European Ticketing
The journey toward a unified digital ticketing landscape did not begin in a vacuum. To understand the current milestones, one must look at the progression of the initiative:
- Late 2021: CER introduces the Ticketing Roadmap, setting the stage for sector-wide collaboration aimed at harmonizing distribution channels and improving passenger rights.
- 2022–2023: Initial technical frameworks are established. Operators begin the long-term process of migrating legacy systems toward more modern, open-standard architectures.
- 2024: A year of significant momentum. Sweden adopts the Online Sales & Distribution Model (OSDM) as its national standard, marking a major success for the initiative. Simultaneously, the focus on interoperability between rail ticketing and timetable data formats like NeTEx (Network Exchange Format) intensifies.
- April 1, 2025: Lithuanian operator LTG Link joins the CIT Agreement on Journey Continuation (AJC), a significant step in bolstering consumer protections.
- April–May 2025: The next critical monitoring survey is scheduled, serving as a final evaluation of phase-one progress before the end-of-year milestone.
The Technological Backbone: The Rise of OSDM
A central pillar of the CER’s strategy is the Online Sales & Distribution Model (OSDM). For years, the European rail market was fragmented by proprietary, siloed booking systems. OSDM acts as the "language" that allows these systems to speak to one another, enabling seamless ticket issuance across borders and operators.
The benefits of OSDM are multi-fold. By providing a standardized interface, it allows retailers and third-party vendors to plug into the rail network with minimal friction. This not only benefits passengers—who can access a wider range of journeys through their preferred platforms—but also strengthens the competitive position of rail as a cohesive product.
Sweden’s decision to adopt OSDM as its national standard in 2024 serves as a blueprint for other nations. As more CER members upgrade their backend systems to be OSDM-compatible, the network effect strengthens. Crucially, the system’s interoperability with the Network Exchange Format (NeTEx) ensures that timetable data and pricing remain synchronized, reducing the risk of "ghost trains" or outdated information appearing on booking engines.
Supporting Data: Protecting the Passenger
While technical standards form the infrastructure of the roadmap, passenger rights form its spirit. The Agreement on Journey Continuation (AJC) is perhaps the most tangible benefit to the average traveler.
Currently, the AJC covers more than 90% of passenger traffic across CER members in the European Union. This agreement provides a vital safety net: should a passenger experience a major delay or disruption while traveling on a multi-operator ticket, they are guaranteed the right to continue their journey at no additional cost.
The inclusion of LTG Link (Lithuania) into this agreement, effective April 1, 2025, is a testament to the expansion of these protections. As the network of AJC signatories grows, the "passenger-first" mandate of the European Commission becomes increasingly realized, fostering greater confidence in long-distance, cross-border rail travel.
Official Responses and Strategic Advocacy
The leadership at CER is clear-eyed about the challenges ahead. In his commentary on the latest report, CER Executive Director Alberto Mazzola emphasized that the sector’s internal efforts must be matched by supportive regulatory frameworks.
"The full and timely implementation of the CER Ticketing Roadmap remains a top priority for CER members," Mazzola stated. However, he was quick to highlight a critical friction point: the Technical Specification for Interoperability (TSI TA). CER is actively lobbying the European Commission to formally incorporate OSDM into the TSI TA Regulation.
The argument is one of investment protection. CER members have committed substantial capital to upgrading systems to meet OSDM standards. Should the Commission finalize the revision of the TSI TA without enshrining OSDM, these investments could be undermined by future regulatory shifts. By locking OSDM into the regulation, the industry seeks to create a stable, long-term legal environment that favors innovation and interoperability over fragmentation.
Implications: The Multimodal Horizon (2026–2030)
As the industry nears the conclusion of the first phase of the roadmap, the focus is already shifting toward the broader context of European mobility. The second phase, slated for 2026–2030, aims to address the integration of rail with other transport modes, including air, bus, and micro-mobility.
The implications of this transition are significant:
- Seamless Mobility: The objective is a single "Mobility-as-a-Service" (MaaS) experience where a traveler can book a trip involving a local tram, a high-speed train, and an airport transfer through a single interface.
- Decarbonization: By making rail the most convenient and reliable option, the CER aims to capture a larger share of the European travel market, directly supporting the European Green Deal’s goal of reducing transport emissions.
- Data Sovereignty: The ongoing development of technical standards will also influence how data is shared across the European transport ecosystem, balancing the need for open access with the protection of commercial interests.
Conclusion: A Test of European Collaboration
The fifth progress report on the CER Ticketing Roadmap is more than just a summary of technical milestones; it is a declaration of intent. It highlights an industry that is actively working to overcome the historical, geographic, and technological barriers that have long defined European rail.
The challenges remain, particularly regarding the speed of implementation across diverse national networks and the necessity of regulatory alignment. Yet, the progress made—from the proliferation of OSDM to the expansion of passenger protections through the AJC—demonstrates that a truly connected European rail network is within reach.
As the industry prepares for the monitoring survey in April and May 2025, all eyes will be on whether the current pace can be sustained. For the European passenger, the promise is clear: the future of travel is not just about the speed of the train, but the ease of the journey from the moment the ticket is booked until the final destination is reached. The CER Ticketing Roadmap remains the engine driving that transformation.
