What time is the tour for assistant station supervisors responsible for storing materials from special work trains?

The correct timing for the tour of assistant station supervisors responsible for storing materials from special work trains is designated as 12 midnight to 8 am. This timing is likely intended to align with operational needs when special work trains may arrive and require their materials to be stored efficiently without interfering with regular service operations during peak hours.

Storing materials during these hours allows for minimal disruption to the daily operations of the station, as these times are typically when passenger traffic is at its lowest. This arrangement ensures that the supervisors can manage the logistics of storing equipment or materials from the work trains effectively and maintain the smooth operation of the station throughout the day.

Therefore, while other time slots may be more convenient for other types of shifts or roles, the early morning hours are specifically designated for this task to optimize efficiency and safety in the station's operations.
