1 Miles operated is in terms of railroad so that a mile of single track is counted the same as a mile of double track. Sidings, turnouts, yard switching mileage, and mileage not operated are excluded. Miles operated under trackage rights provided by another (owning) railroad are included.
2 In 1999, most of Conrail's rail lines and facilities were divided between CSX and Norfolk Southern. Nevertheless, Conrail continues to operate some lines and facilities in the Philadelphia and Detroit metropolitan areas and in New Jersey.
