You can also go south of DC to Fredericksburg, VA (about halfway between DC and Richmond) on Virginia Railway Express (VRE). I'm almost definite there is commuter rail in the Boston area on MBTA north of Boston on Amtrak's Downeaster corridor, but I don't know which line that is or how far it goes without looking it up.
To my knowledge, the VRE, MARC, and Shore Line East only run on weekdays. (I know the first two only run weekdays.) In addition, the VRE and I think Shore Line East only or primarily run peak periods on weekdays. (The same is true with the MARC Camden Line between DC and Baltimore, but the MARC Penn Line - the line that operates on the NEC - does run in the middle of the day, particularly between DC and Baltimore.) In addition, the SEPTA R2 has limited service to Newark, DE on weekdays, only runs to Wilmington on Saturdays, and does not go to Wilmington (or Newark) on Sundays.

Here I thought it was an exercise in determining which of us is the biggest train schedule nerd!
I may look up the answer later when I get home, but obviously the key factor is the headways for each of the commuter rail services, especially in the middle of the day in the middle of the NEC. Assuming weekday ridership, key schedule factors include:
- NJT NEC Line: 30-40 minute midday headways between New York and Trenton
- SEPTA R7 (East) Line: 60 minute midday headways between Trenton and Philadelphia
- MARC Penn Line: 60 minute midday/early evening headways between Baltimore and Washington (last southbound train leaves Aberdeen, MD shortly after 3 PM in most current MARC Penn Line timetable; there are a handful of southbound, evening trains between Baltimore and Washington)
I'm not sure, but it's possible it may be easier to make that NEC commuter rail day trip going northbound rather than southbound. Regardless whether that's true or not, I have a feeling one direction is probably somewhat easier to do than the other direction.
