Timetables are a one page concise way of describing all train operations on that route, station services, amenities, connecting services, and the entire train's route. I for one do not want to ride a northbound train at DC coming from deep in Virginia, North Carolina, or Georgia, as they tend to be late. Trains are not airplanes. Most of the Intercity bus industry does not produce timetables and it is dying rapidly. Hipster and Smartphone focused Megabus is dead.
As for times, it did not require having to initiate making a fake reservation to find it, nor deciphering multiple locations in a city and knowing station names, like Burlington, Vermont or deciphering Bloomington from Normal, IL and not be told no service exists.
The national timetable also had all station addresses, diagrams of sleepers, nationwide maps.
It now requires searches all over the website, which few non-railfans, including myself, have little patience for.
