What is imperative during the hours when trains are scheduled between 10:00 PM and 6:00 AM?

During the hours between 10:00 PM and 6:00 AM, it is particularly important for conductors to hold the door open at each station until the scheduled departure time to ensure that all passengers have the opportunity to board or alight, especially since this period may have fewer trains and passengers might be less familiar with the schedules. Holding the doors open creates a safer and more accommodating environment, as it allows for potential delays in passenger movement that might occur during these quieter hours. This practice directly addresses the needs of passengers who may be traveling late at night or early in the morning.

Other options, while they may have relevance in specific situations, do not focus on the immediate needs of passenger safety and convenience during this time. Announcing each station is typically a practice for all hours but may not be as critical during quieter times when fewer passengers are boarding. Reducing train speeds can be important in many circumstances but is not universally mandated during these hours. Lastly, requiring all trains to stop at every station could increase travel time unnecessarily and is not a standard practice for operational efficiency.
