Unless everyone in Wilmington is planning on working in Raleigh, the main question still remains: Who pays for the rail line?
Take a cursory look at the taxes people who live in the New York MTA area pay and you'll start to see what's in your future if this comes. The MTA is huge, with a couple of hundred thousand riders every day and THEY can't support themselves. But the taxes are some of the highest local taxes in the nation.
BTW, the people in Fayetteville and Goldsboro have just as much right to live in their town and work in Raleigh as you do....maybe moreso for Goldsboro, as they already have a sizeable population driving to and from Raleigh every day. This is such a very bad, very expensive idea however, that few of them will opt for that "benefit."
