Solution Overview

Take a look at the opportunities
you have with UniAC[2]

We take safety & security to a higher level

The fulfillment of highest safety levels (SIL4) for track vaccancy systems are understood as industry standard nowadays.

During the development of UniAC[2] voestalpine decided to go one step further and include as well cybersecurity measures (authentication, authorization, integrity, cryptography) that would address the identified vulnerabilities & threats in the newly developed Axle Counting System UniAC[2].

attack surface

Physical and functional interfaces that can be accessed and exposed to potential attack are minimized. With dominant use of embedded firmware and legacy hardware (no COTS and OS in safety and security area) UniAC[2] is flexible with network segmentation and access control.

in depth

Multiple layers security mechanism of security and detection. Implement of good security practices in Layer 2 (hardware) and Layer 7 (application software). Additionally, usage of layer 3 protection (firewall) with separation of connected networks is possible.

by design

Implemented based on extensive separation of safety and security functions.

Existing Solutions

Upgrade your Track Vaccancy Solution to ensure greatest performance and safety

We will support you in finding
the easiest way of integration

  • Much higher reliability than in track circuits, resulting from the lack of connection with rails (resistant to lightning damage)
  • Axle Counters are proved more reliable than track circuits (over 5 – 6 times, based on long time monitoring)
  • Resistant to poor ballast and track conditions
  • Resistant to climatic influence (track circuits are not reliable in wet conditions)
  • Reduction of maintenance costs
  • Possibility of building long distance sections and more turnouts within one section
  • More information for other systems
    (speed, number of axles, …)
  • Application of Axle Counter is much cheaper than track circuits

All of this in the easiest possible way due to highly flexible and configurable interfaces.

Depending on your existing signaling system we support you in finding the easiest way of integrating our Axle Counting System UniAC[2] into your application. Together we ensure that an existing and working signaling system can remain installed and you can limit your investments, without making compromises in regard to safety or performance of the track vaccancy technology used.

The Axle Counting System will be customized and adapted to your local requirements through the flexibility of UniAC[2]. However, all of this will not influence the safety, as we have made sure and also proved through the SIL4 assessment of TÜV SÜD in Braunschweig that all of our delivered configurations will reach the requested safety levels.
Finally, all of this will be supported by delivering a full set of documents including electrical wiring diagrams, making it easy for you to adapt the existing application.
