The format change is an improvement.
HOWEVER. The Northeast Corridor timetable, and the Virgnia Service timetable, both suffer from the multiplicity of "certain days of the week only" schedules.
I think it would be wise for Amtrak to start printing separate Weekday, Saturday, and Sunday schedules for the NEC. Or at least separate Weekday and Weekend schedules. There is too much divergence.
#83/#93, the train which goes to Newport News only on Fridays; #196/136, which goes to Springfield only on Fridays; #658, the Keystone which only operates on Fridays; and #134, which only operates on Thursdays and Fridays -- why? -- these could probably remain in the weekday schedule.
But there are just too many "Mo-Fr", "Sa", and "Su" columns. It's confusing. And that's before you get to the footnotes saying "This train stops at different times on Saturdays and Sundays".
There are only four "Daily" train columns in the Southbound NEC schedules: the Carolinian, the Pennsylvanian, and #67 (which is listed twice!).
There are only four "Daily" train columns in the Northbound NEC schedules, too: the Pennsylvanian again, #198, and #66 (which is also listed twice).
Accordingly, it really wouldn't make the NEC timetables much longer if the Weekday and Weekend timetables were separated; it might add two pages total. Separating weekend from weekday for the Virginia timetables would require a few more pages, but I think it would be worth it....
