What action is required if the actual HPT matches the scheduled HPT for Z, Q, or P trains?

If the actual High-Priority Time (HPT) matches the scheduled HPT for Z, Q, or P trains, no additional action is needed because this indicates that the train is operating on schedule as planned. The alignment of the actual and scheduled HPT signifies that the train is meeting its expected performance, and it can continue along its route without requiring any modifications, interventions, or reporting. Maintaining the schedule is vital for operational efficiency, especially for freight trains categorized as high-priority. Thus, confirming that the train is on time alleviates the need for isolating locomotives, notifying a yardmaster, or adjusting brake settings, all of which are measures taken only when there is a discrepancy in performance.
