Summary

This layer contains railroads in the US. This line file is intended for medium scale thematic mapping and analysis.

Description

            

The spatial data were obtained from the National Atlas of the United States and are current as of 2013. This file contains railroads designated by the Federal Railroad Administration. 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. The attributes were modified to include owner(s), mark(s), length, and additional information. The coordinate system of this data is WGS 1984.
