I'd love to see CSX Peninsula Subdivision in Virginia. It's not extremely busy, but it does pass through some historical locales (Williamsburg, Yorktown), as well as have 70-odd miles of mainline, with a rather large yard, and coal piers in Newport News, and a yard in Richmond along with a TRANSFLO terminal. CSX moves roughly 20 millions tons of coal through this route every year. It's also serviced by Amtrak's Northeast Regional. I can see this made maybe as a low cost dlc. I would also like to see a Norfolk Southern route.
