Background Information
Sample map Sample Map
A railroad is a set of parallel rails on which a train runs. Railroads in the United States carry freight and passengers on more than 200,000 miles of track. The Federal Railroad Administration of the U.S. Department of Transportation is responsible for overseeing railroad safety, planning, and development in the United States.

The Railroads of the United States map layer shows the major railroads of the conterminous United States and Alaska that can be represented at a map scale of 1:2,000,000 (1 inch on a map at that scale equals about 31.6 miles on the land surface). Some small railroads and closely parallel tracks cannot be portrayed at this scale. Descriptive information for each section of track includes the names of up to three railroad lines that own the track, as well as the Association of American Railroads reporting mark used to identify each railroad. This map layer was compiled by the National Atlas of the United States®.
