I would love to see the CSX River Subdivison that runs from North Bergen, New Jersey to Selkirk, NY. Its an awesome rail line, lots of beautiful scenery and since it parallels the Hudson River (hence the name "River Line" it can make for some beautiful shots, and i think it could make for a awesome DLC. The line use to be owned by several railroads before CSX took over. New York Central was one of the owners as well as Conrail. The Yard in North Bergen would make for some awesome switching missions/jobs, ect. and with it being over 132 miles long, it would make for an awesome DLC!
