Amtrak timetable changes taking place in October 2017:
Pacific Surfliners (effective 10/9/17): Many changes to train numbers, and also which trains have northern terminus at Los Angeles, Goleta, or San Luis Obispo.
Northeast Regional - Virginia (effective 10/31/17): Includes new Roanoke extension.
Still expected are new timetables for Ethan Allen Express (whose timetable folder is shared with the Vermonter) and also the Empire Service since changes affecting the Ethan Allen Express also affect the New York-Albany corridor. The change is coming, but while Amtrak's scheduling department knows about it, Amtrak's IT department does not.
For November there may be changes to long distance train schedules consistent with the move from Daylight Savings Time to Standard Time.
