*Later on, what should have been done/should be done is a swap to give CSX either a bridge or a tunnel at Dahlgren/La Plata in exchange for VA (or an agency) getting control of Dahlgren Junction to the junction in Washington (with local freight from CSX and any access-rights freight from NS allowed but all other through freight being sent around DC). Ideally you'd stretch that to just south of Fredericksburg/Spotsylvania with a bypass there as well, and voila, the Fredericksburg Line has a near-blank check while VA could then (in theory) extend as many Regionals as they wanted down to FBG without much ado. At that point I think we enter into "negotiate with Amtrak to move their facilities from Ivy City to a nice, new yard in Spotsylvania County"... Yes, I wish this would happen, and it probably isn't impossibly expensive with federal matching funds...just obnoxiously so.
