I'm kinda wondering which trains will be MARC sets (which means bathrooms are likely at the cab car and next to the engine). Assuming Amtrak uses them only on the NEC, I went through the schedule.
During the holiday week, Amtrak may use cars
borrowed from commuter rail agencies to run
“Holiday Extra” trains. (These trains are numbered
1054 and higher in the Thanksgiving timetable.)
We recognize that some of the borrowed cars
might not be what you expect from our Amtrak
fleet. “Holiday Extra” trains will have fewer
restrooms and may not offer food service.
Oh! Nice. But they use "Holiday Extra" on Sunday only and "Northeast Corridor Extra" everywhere else. I've starred the "Holiday Extras".

This also makes me wonder... MARC II cars are qualified to run from Linchburg to Boston?!?
