Innovation at InnoTrans 2026: UniAC[2] sets new benchmarks as a contribution to standardized, EULYNX-oriented signalling systems

The UniAC[2] system is based on a clearly structured separation into functional components. The UniAS[2] wheel sensor ensures reliable wheel detection in the field, even under demanding environmental conditions, while the AXM module provides the safety-related evaluation, counting logic, and system integration.

This functional separation aligns with EULYNX objectives of structuring systems along well-defined interfaces. The architecture enables a clear allocation of functions and supports integration into standardized signalling and interlocking environments.

A key focus of the system is the use of standardized interfaces combined with a consistent system logic. UniAC[2] thereby supports core EULYNX principles: reduction of interface diversity, clear system boundaries, and simplified maintenance of system components.

Pre-configured system components and plug-and-play capability help to minimize integration effort and facilitate implementation into existing or new digital interlocking architectures. This approach reduces dependencies on proprietary solutions and supports interoperable system landscapes.

During operation, UniAC[2] addresses key requirements of modern infrastructure managers. Hot-swappable modules allow the replacement of components without additional configuration steps, contributing to high system availability and reduced maintenance effort in line with EULYNX-oriented system environments.

Thanks to its modular design, the system can be flexibly extended. New counting points can be integrated without fundamental changes to existing system structures – a key aspect for scalable and future-proof railway infrastructures.
