Central. Following approval by the Surface Transportation Board, CSX and NS took control in August 1998, and on June 1, 1999 began operating their respective portions of Conrail. The old company remains a jointly-owned subsidiary, with CSX and NS owning respectively 42 percent and 58 percent of its stock, corresponding to how much of Conrail's assets they acquired. Each parent, however, has an equal voting interest. The primary asset retained by Conrail is ownership of the three Shared Assets Areas in New Jersey, Philadelphia, and Detroit. Both CSX and NS have the right to serve all shippers in these areas, paying Conrail for the cost of maintaining and improving trackage. They also make use of Conrail to perform switching and terminal services within the areas, but not as a common carrier, since contracts are signed between shippers and CSX or NS. Conrail also retains various support facilities including maintenance-of-way and training, as well as a 51 percent share in the Indiana Harbor Belt Railroad.
