Seamless cross-border railway operations require more than just infrastructure and technology; they demand effective communication. Language barriers between train drivers and signallers have long posed challenges to efficiency, safety and interoperability. However, the railway sector is actively addressing this issue through innovative language tools and digital solutions.

At the Train Driver Communication Conference held on 6 March at UIC Headquarters, experts, policymakers and railway stakeholders came together to discuss the latest advances when it comes to breaking down language barriers in rail operation. Moderated by Paul Hodgson (CFL Cargo), the conference showcased the ongoing projects, key milestones and future ambitions of railway language interoperability.

The insightful discussions were led by several speakers, including Juraj Maliacek (RNE), Parinaz Bazeghi (UIC), Cyril Chambourg (Viseo), Annick Jeiziner (SBB Cargo International), Riccardo Ioncoli (RFI), Simona Garbuglia (RFI), Silva Kristan (SZI), Caterina Caramuta (University of Trieste), Estelle Bacconnier (DG MOVE), Marcel de Haye (CER), Frédéric Hénon (UIC) and Roland Rieder (BLS Cargo).

Key highlights:

• Predefined messages for rail operations – UIC & RNE have collaborated on a structured list of pre-defined messages to standardise communication between train drivers and signallers. This list will be soon available through an IRS.

• Translate4Rail & beyond – There are currently several active language initiatives in the sector, exploring various technologies and focus areas to enhance communication. During the conference, an overview of the major initiatives and ongoing pilots was presented, highlighting their objectives and progress.

• Testing & real-world impact – Case studies from Brig-Domodossola were presented, incorporating the perspectives of drivers and signallers. The discussion focused on exploring the technical aspects of connecting the tool to the driver’s cabin on the one hand, and the dedicated activities for training signallers and connecting the tool to the dispatcher console on the other. In addition, insights were shared on the Interreg T4RAIL-IT-SL Italy-Slovenia pilot project, which integrates digital communication and is going to test Translate4Rail in operation to enhance interoperability, improve efficiency and reduce costs.

• Regulatory support & industry collaboration – Panel discussions with DG MOVE, CER, UIC, RNE and BLS Cargo emphasised the importance of harmonised regulations, investment in digital tools, and continuous testing to drive progress. The role of FRMCS in integrating language solutions for the next generation of railway communications was also discussed.

As we reflect on the insights shared during the Train Driver Communication Conference, one key message stands out: collaboration is essential. By working together towards a common goal, we can drive real progress towards overcoming language barriers in railway operations.

However, funding remains a challenge, and innovation will be crucial in shaping the next steps. The Translate4Rail (T4R) tool has already demonstrated its potential – not only for cross-border communication, but also as a training tool for train drivers and signallers. Its adaptability allows it to be tailored for various solutions across the railway sector.

The technology is already available – now, the focus must be on integrating these solutions into future railway initiatives. As we look ahead to upcoming activities within ERJU (Europe’s Rail Joint Undertaking) and FRMCS (Future Railway Mobile Communication System), we must ensure that language interoperability remains a core topic in the evolution of digital railway systems.
