| Background Information | |
Sample Map
The One Million-Scale Railroads map layer shows the major railroads of the conterminous United States and Alaska that can be represented at a map scale of 1:1,000,000 (1 inch on a map at that scale equals about 15.8 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. An older map layer showing Two Million-Scale Railroads as of 2005 is also available. This map layer was compiled by the National Atlas of the United States. In cooperation with national mapping programs in Canada and Mexico, we also produce a map layer of railroads across North America. |
