Background Information |
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®. |
