Conrail Shared Assets Operations is an Americanrailroad company. It operates three networks—the North Jersey, South Jersey/Philadelphia, and Detroit Shared Assets Areas, where it serves as a local carrier and switching company for CSX Transportation and the Norfolk Southern Railway. When most of the former Conrail's track was split between these two railroads, the three shared assets areas (a total of about 1,200 miles of track) were kept separate to avoid giving one railroad an advantage in those areas.
