Amtrak has another section of the NEC without cantonaries I’m VA that runs from Washington DC-Newport News, Norfolk, Roanoke Amtrak runs the Northeast Regional, Carolinian, Silver Star, Silver Meteor, and Auto Train the engine that would come with this route would be the Amtrak P40 Amfleet I coach’s Amfleet I Northeast Regional cafe and Viewliner baggage
For reference, territories past Washington and Boston is not considered the Northeast Corridor, anything in between DC and Boston is the NEC. Some of those routes would be cool though!
