Axle counting systems have established themselves for years as a reliable alternative to conventional track circuits. They circumvent typical weaknesses such as contamination from ballast, rust, weathering, or aging components. With UniAC[2] from voestalpine Railway Systems, this proven principle is further developed: by combining it with a plug-and-play solution, a high-performance detection system is created that not only significantly reduces installation time and configuration risks but also improves ease of maintenance.

Quick installation, minimized risk
Pre-configured sensor units, standardized cable interfaces and interoperable internal modules ensure that significantly fewer components need to be adapted or calibrated on site.
The result:
- Lower risk of misconfigurations.
- Reduced commissioning times.
- Consistent system behavior across different locations.
From a technical point of view, rapid integration also offers advantages, as it reduces the number of design validation cycles and allows for more efficient creation of safety documentation.

Maintenance reimagined: Hot-swapping for maximum availability
The UniAC[2] axle counting system features hot-swappable modules . These modules can be replaced during operation without requiring reconfiguration. This ensures smooth and reliable operation – even in environmentally challenging environments or under irregular transport conditions. Maintenance planning becomes more predictable, and the mean time to repair (MTTR) is also reduced.
Scalability for growing rail networks
The rail network is constantly expanding – stations are growing, new sidings are being added, and routes are changing. The UniAC[2] axle counting system is designed to adapt to this development. Thanks to its modular design , additional detection points can be added without having to redesign the entire 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 operation.
The plug-and-play axle counting system from voestalpine Railway Systems is not just a new technology category, but the logical further development of modern axle counting systems that focus on modularity, interoperability, environmental compatibility and calibration-free installation.
The advantages at a glance:
- Improved installation efficiency.
- Higher reliability.
- Reduced maintenance requirements.
- Flexible scalability.

UniAC [2] makes axle counting simpler, faster, and more robust. Its integration into a plug-and-play architecture makes the axle counting system a future-proof solution for modern railway networks, while also offering a longer lifespan over its entire life cycle.
