The use of instrumented revenue vehicle data to calculate track geometry parameters

This paper discusses the instrumentation and analysis methods required to transform rolling stock performance data to track geometry parameters. The system described in this paper has been implemented on Instrumented Revenue Vehicles (IRVs) at the Australian Rail Track Corporation (ARTC) Hunter Valley network in NSW Australia. The IRV platform provides a novel method to continuously and autonomously collect valuable track condition and rolling stock operational information. The detection of track defects using IRV data is based on the measurement of dynamic responses of the wagon. In practice, track geometry maintenance is generally conducted to minimise rolling stock responses leading to track loading and potential derailments. The addition of geometry parameters to the IRV system enables the detection of track defects at low speeds when vehicle dynamics are reduced or when the wagon is in an unloaded condition. The paper provides examples of how IRV track geometry parameters relate to wagon dynamic responses and discusses how it can be used for a variety of track maintenance activities.
