UniAC[2]: Plug-and-Play brings new efficiency to axle counting

18 May 2026 |

Axle counting systems have long been established as a reliable alternative to traditional track circuits. They avoid typical vulnerabilities such as ballast contamination, rust, weather-disruption, and component aging. With UniAC[2] from voestalpine Railway Systems, this proven principle is further refined: by combining it with a plug-and-play solution, a high-performance detection system is created that not only significantly cuts installation time and configuration risk but also enhances maintenance.

Quick installation, minimized risk

Pre-adjusted sensor units, standardized cable interfaces, and interoperable indoor modules ensure that significantly fewer components need to be adjusted or calibrated on-site.

The result:

Reduced risk of misconfigurations.
Shorter commissioning times.
Consistent system behavior across different locations.

From an engineering point of view, rapid integration also offers advantages, as it reduces the number of design validation cycles and allows safety certifications to be prepared more efficiently.

Maintenance reimagined: Hot-swap for maximum availability

The UniAC[2] axle counting system features hot-swappable modules. These modules can be replaced during operation without the need for re-configuring. This ensures smooth and reliable operation — even in a polluted environment or under intermittent transportation conditions. Maintenance planning becomes more predictable, and mean time to repair (MTTR) is reduced.

Scalability for growing rail networks

Rail network gets updated over and over — stations bulge, new sidings are added, layouts change. The UniAC[2] axle counting system is designed to adapt to these developments. Thanks to its modular design, additional detection points can be added without the need to redesign the whole system. As long as mechanical and electrical standards are met, the UniAC[2] axle counting system can be expanded almost indefinitely — without compromising safety or operations.

A plug-and-play axle counting system is not just a new technology category, but rather the natural next step of modern axle counter methods that prioritize modularity, interoperability, environmental durability, and calibration-free installation.

The advantages at a glance:

Improved installation efficiency.
Higher reliability.
Reduced maintenance requirements.
Flexible scalability.

With UniAC[2], axle counting becomes simpler, faster, and more reliable. Its integration into a plug-and-play architecture makes the axle counting system a future-proof solution for modern rail networks, offering a longer service life throughout its entire lifecycle.
