- Description:
-
- Abstract:
-
This map layer includes railroads in the conterminous United States and
Alaska. This is a replacement for the December 1998 map layer.
- Purpose:
-
These data are intended for geographic display and analysis at the
national level, and for large regional areas. The data should be
displayed and analyzed at scales appropriate for 1:2,000,000 data. No
responsibility is assumed by the National Atlas of the United States in
the use of these data.

- Process_Description:
-
The NRN data were loaded into Arc/INFO and the list of attributes was
edited to include a maximum of three railroad owner names and their
corresponding reporting marks. Additional railroad owner names were
obtained from the AAR, DP, TC, and PW sources. The sources DP and
NRHS were used to identify abandoned railroads and rail lines no
longer in existence, which were then deleted. The attributes were
reorganized, so that for tracks with multiple owners, the largest
railroad is listed as Rrowner1, with the next smaller railroad listed
as Rrowner2, and the smallest of the three railroads, if any, listed
as Rrowner3. Some tracks were adjusted inland from open water using
Atlas_States as a guide. Tracks were generalized, particularly in
congested areas, and merged where they run closely parallel to one
another. The file was saved as a Shapefile.
