The blog focuses on ERTMS, ETCS, ERTMS/ATO, DATO, railway automation, migration, interoperability and digital railway operations from an architectural and industrial perspective.

Railway automation is often presented through individual technologies: automatic train operation, cab signalling, moving block, remote driving or unattended train operation. These technologies matter, but they only become useful when they are integrated into a coherent railway system.

This is the perspective of Voie Libre.

The objective is to look beyond isolated functions and understand how protection, automatic driving, traffic management, rolling stock, infrastructure, data, telecommunications, cybersecurity, operational rules and safety assurance can evolve together.

The central question is not only whether trains can drive automatically. It is how Europe can build a digital, automated and interoperable railway architecture that is deployable, governable and valuable for real operations.

The name “Voie Libre” is a French signalling aspect meaning that the train is authorised to proceed. It also reflects the purpose of this blog: to open a path towards a more capable, more digital and more interoperable railway system.

Voie Libre is written by Bastian Simoni, a railway system architect working at the intersection of signalling, automation and European railway innovation programmes.
