What information is provided by a Timetable?

A timetable is primarily designed to provide essential information regarding the schedule of train services. This includes the specific arrival and departure times at listed terminals and various intermediate stations. It allows passengers and operators to know when trains are expected to arrive and depart, which is crucial for planning and coordination in train operations.

The timetable also assists in ensuring that trains keep to a reliable schedule, improving efficiency and reducing potential delays. While a timetable may sometimes indirectly imply factors like the duration of rides through the times listed, its primary purpose is to communicate the exact schedule for train services. This makes "arrival and departure times from listed terminals and intermediate stations" the most relevant and correct answer.
