On NE Regional between DC>NYC in Business Class; change to Acela?
I'm on the NE Regional from DC to NYC (Union Station > Penn Station). Would it be at all possible to change to Acela at no charge, by maybe asking the Union Station staff if they can change me? It looks like there's an Acela going to NYC shortly after my regional train leaves, and it's shorter by ~1 hour. I'm in paid business class, for the NE regional service, and this is work travel.
Thanks!
