During which time is it least important for local and express trains to meet at transfer points?

The least important time for local and express trains to meet at transfer points is during non-peak hours. During these times, train frequency is generally lower, and there is less ridership. As a result, the need for connections between local and express services diminishes, because fewer passengers rely on these transfers to make their journeys efficient.

In contrast, rush hours are crucial for transfers since many commuters depend on both local and express trains to optimize their travel times. At night, though trains may run less frequently, passengers still require connections, making it less ideal for trains to operate independently. During holidays, the travel patterns can also differ, but there is still a significant number of people traveling who may benefit from connections. Therefore, non-peak hours represent a period when the logistical importance of synchronizing local and express trains at transfer points is reduced.
