Miles of Freight Railroad Operated by Class of Railroad


According to the Association of American Railroads, a Class I railroad in 2012 is a railroad with operating revenues of at least $452.7 million. A Regional railroad is a non-Class I, line-haul, freight railroad operating 350 or more miles of road or with revenues of at least $40 million or both.  A Local railroad is a railroad which is neither a Class I nor a Regional railroad, and is engaged primarily in line-haul service. A Switching and terminal railroad is a non-Class I railroad engaged primarily in switching and/or terminal services for other railroads. This table is not comparable to past versions of this table. 


1 Miles operated under trackage rights provided by another (owning) railroad are excluded. Miles of railroad operated is synonymous with route-miles (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.  Year-to-year changes in miles operated are due to both changes in track mileage and changes in the number of railroads with rights for the same track.

2 Refers to non-Class I, Canadian-owned lines.

3 Excludes 656 miles of track owned by Amtrak.
