Banedanmark’s Aarhus Station: Digital Rail Upgrade by 2027

Introduction

In October, Banedanmark initiated the replacement of the existing signalling system at Aarhus Central Station with a new, fully digital system, aiming to enhance train traffic flow and reduce delays. The project, designed to streamline operations at the terminus station, is slated for full completion by 2027.

Aarhus Central Station Digital Upgrade

The project at Aarhus Central Station involves the installation of a new digital signalling system. According to Jan Hertzberg, project manager at Banedanmark, the station’s configuration as a terminus, where all trains share routes, presents operational challenges. The digital system aims to address these challenges by allowing for more efficient management of train movements.

Technology Implementation

The new system incorporates track-based components that facilitate direct communication between trains and the control tower. Traffic controllers will monitor train movements in real-time, using screens to provide a clear overview. The upgrade includes the replacement of the current system with passive and active components, such as balises and axle counters, supported by the installation of cable ducts and cabling.

Operational Enhancements

The digital system is designed to enable trains to operate safely closer together, by dynamically calculating safe distances more accurately than the previous system. The transition to the new system will involve the removal of the old signals, which should reduce delays caused by equipment wear. Early next year, train operations using the new digital system will begin.

Project Timeline

The project began six months ago and is scheduled to be fully operational by 2027. Track upgrades on the second half of the station will commence to implement the passive and active components. The digital signalling system will guide electric trains to and from Aarhus Central Station. The system utilizes wireless communication to manage train speed, routes, and stopping points.

Conclusion

The ongoing project at Aarhus Central Station, led by Banedanmark, involves a comprehensive upgrade of the signalling system. The transition to the new digital system is expected to improve traffic flow and reduce delays, with full implementation planned by 2027.
