Every year, thousands of track circuit failures are reported by railway infrastructure managers in Europe and worldwide, resulting in significant delays which can also lead to substantial economic costs and penalties.
For this reason, the ability to detect and diagnose the health of track circuits to prevent or provide a fast response to these failures, can generate a significant benefit for infrastructure managers.
In many countries, a process of periodic manual inspection of wayside assets (including track circuits) is in place, but the benefits of this strategy are limited by several factors related to safety, the time required to perform the inspection, and difficulties associated with making manual measurements.
With the purpose of minimizing economic loss and operational delay, as well as offering railway infrastructure managers a tool that can provide an automated and effective maintenance strategy, ERTMS Solutions has designed the TrackCircuitLifeCheck (TLC).
The TrackCircuitLifeCheck is a track circuit measurement instrument that can be installed on track inspection or commercial trains to automatically diagnose AC and pulsed track circuits, thus enabling a preventive maintenance strategy, based on the analysis of multi-pass data from each track circuit over time, and the application of standard deviation analysis.
