Problem 43664. Use a timetable to analyze a train timetable (Part 1)

This problem needs more test cases, and probably the current time should be added. Or it should be declared that the timetable does not contain past trips.

I notice that several problem groups have duplicates.
For example "R2016b Feature Challenge" with Use a timetable series, or "Strings III" with Cat, Meowcat and Concatenation or longest common semi-substring problems.

Train timetables in the test suite for this problem are odd. Some train departure times on same day to the same destination are not in chronological order.
