Banedanmark, Denmark: Digital ERTMS Solutions & Rail Efficiency

Introduction

Banedanmark’s nationwide signalling programme in Denmark, which involves replacing over 50 legacy signalling systems across 2,600 kilometers of track, exemplifies the application of digital delivery models in European Rail Traffic Management System (ERTMS) projects.

Challenges of ERTMS Implementation

The implementation of the European Rail Traffic Management System (ERTMS) faces challenges due to diverse legacy systems, technical specifications, and regulatory frameworks across different countries. These factors lead to significant integration and compliance hurdles, particularly in cross-border corridors. A core challenge is integrating ERTMS with legacy signalling and control systems, which were often not designed for interoperability.

Digital Solutions in ERTMS Projects

Digitalization, through model-based design, connected data environments, and digital twins, provides a scalable approach to address the complexities of ERTMS projects. Integrated 3D modelling enables early-stage clash detection and design validation. Common data environments offer a centralized platform for data sharing and collaboration. Construction simulation tools utilizing 4D and 5D modeling aid in planning construction sequencing and cost control. Digital twins enhance system understanding by simulating signaling behavior and asset interactions.

Banedanmark’s Digital Approach

Banedanmark adopted a fully digital delivery model for its nationwide signalling program. This approach utilized integrated 3D modeling and a connected data environment to coordinate design and maintain a single source of truth. Digital twins were employed for signaling logic simulation and asset interaction, reducing on-site testing needs. Additionally, 4D construction simulation supported precise planning and minimized disruptions to live operations. This strategy enhanced delivery efficiency and stakeholder coordination.

The Future of ERTMS

The European Union’s funding instruments, such as the Connecting Europe Facility (CEF) and the Recovery and Resilience Facility (RRF), are prioritizing rail modernization. These funding opportunities can offset transformation costs while aligning with EU goals for sustainability and interoperability.

Conclusion

The integration of ERTMS faces challenges due to varying legacy systems, but digital solutions offer a scalable approach to address these complexities. Banedanmark’s project in Denmark showcases the successful application of digital tools in large-scale ERTMS programs.
