en.Wedoany.com Reported - The UniAC[2] axle counting system, launched by voestalpine Railway Systems, uses wheel sensors installed on the track to detect train wheelsets, determining whether a track section is occupied or clear by tracking entry and exit records. Unlike traditional track circuits that rely on the conductivity of the rails, this technology provides reliable detection results even in harsh environments such as poor ballast conditions, electromagnetic interference, or extreme weather.
The railway applications supported by the UniAC[2] system include track occupancy detection on main lines and at stations, level crossing protection, activation and triggering systems, block interlocking, and auxiliary track occupancy detection for Communication-Based Train Control (CBTC) systems. It can also be customized to meet specific customer requirements.
The system consists of indoor and outdoor modules. The indoor module is located in the signal room or an outdoor cabinet beside the track, while the outdoor part comprises UniAS wheel sensors with detachable cables and modular flexible mounting clamps that can be installed on almost any rail profile. The axle counting system integrates modern technology, high reliability, and ease of integration through the UniAC[2].
Key features of the UniAC[2] axle counting system include: readiness for integration with EULYNX Baseline 4, enabling secure communication without relying on additional encryption devices; a single universal multi-purpose module (AXM) performing all necessary system functions, reducing spare parts inventory and simplifying logistics; embedded cybersecurity features including an encryption authentication module and hardware-level isolation for safety and security; reliable operation across extended temperature ranges for indoor installation (-40°C to +80°C) and outdoor installation (-40°C to +85°C), with sensors certified to IP68; configuration based on a plug-and-play concept using the Application Architect tool with a graphical user interface, reducing installation time and cable length; and redundant design at the hardware, software, and communication layers to enhance system availability.
As a railway infrastructure supplier, voestalpine Railway Systems covers everything from switches and track systems to digital signaling and monitoring systems, providing integrated solutions where components work together, full lifecycle support from design to digital upgrade, and global project experience.
