Point-to-Point Running Time and Schedule Accuracy Analysis
One major Northeastern passenger railroad had a period during late 2013 when train running times between interlocking control points were changing on a weekly basis due to moving infrastructure upgrade and maintenance projects. We were responsible for the near real-time analysis of track circuit occupancy data from train tracker software to determine whether sufficient running time was being provided in the operating schedules to ensure reliable operation and accurate arrival time predictions. We informed the train scheduling process by provide a scientific basis for running time adjustments by developing lateness, running time, variability, and delay cause analysis, and provided heat-map visualizations for senior management.
