When are trains prohibited from being delayed for connections during non-commission hours?

Trains are prohibited from being delayed for connections during non-commission hours when headways are up to 10 minutes. This rule is in place to ensure operational efficiency and to minimize delays. During non-commission hours, train services are typically operating on a reduced schedule, and short headways—such as those of 10 minutes or less—indicate a high frequency of service. Maintaining on-time performance during these periods is crucial because delays can compound quickly, leading to broader disruptions within the schedule.

Therefore, allowing delays for connections when trains are running with such short intervals would undermine the purpose of running an efficient service during non-commission hours. In contrast, longer headways or no connections at all would not have the same impact on the overall timetable, reinforcing the necessity of this specific regulation for headways up to 10 minutes.
