| Abstract | National Research Council Canada in collaboration with Transport Canada, Canadian Rail Research Laboratory, and Canadian National Railway initiated a research project to assess the potential of two measurement technologies - a rolling deflection measurement system and instrumented wheelsets - for monitoring track condition. This paper presents a sample of data collected over one mile of track during this study and interprets the physical meaning of its variation over different track features. The measurements from these systems represent actual field conditions as recorded from under a loaded rail car and at operating speed. The measurements from the rolling deflection system were used to quantify the stiffness of track whereas the instrumented wheelsets were used to identify locations where there was excessive vertical, lateral, or longitudinal forces. The analysis of the data suggested that the information provided by these two systems was different than the measurements from existing inspection methods such as the track geometry car, and can be potentially used for performance-based assessment of railway tracks. |
