U.S. National Transportation Atlas Railroads represents a comprehensive database of the nation's railway system at 1:100,000 scale. This shapefile covers only the south central and the eastern half of the US. NBII-SAIN (ed.) created this file by clipping from ESRI 2002 rail100k.shp. NBII-SAIN website: (http://sain.nbii.gov/).
Largest scale when displaying the data: 1:50,000. No data for Alaska or Hawaii.

U.S. National Transportation Atlas Railroads provides location and partial attribute information for use in national and regional network analysis applications.
Attribute and geospatial data
The general processing steps for the creation of the National Rail Network 1:100,000: The FRARAIL (Federal Railroad Administration, 1120 Vermont Ave., N.W. Washington, DC 20590) data and the VOLPERAIL (John A. Volpe National Transportation Systems Center, Service Assessment Division, DTS-49, 55 Broadway Cambridge, MA 02142) data were combined using conflation algorithms in both TransCAD and ARC/INFO. Manual adjustments were then made to the resulting spatial database. The Official Railway Guide provided by the Rail Industry and published by K-111 Directory Corp. New York, NY contributed railroad line identification ownership and track rights. Data quality report: A partial quality control evaluation of the accuracy of the attributes was performed on the database. The likelihood of attribute errors is greater in the urban than in the rural areas. There are no attributes listed for sidings. The railroad ownership and trackage rights attributes are not complete. The database is interconnected and is a flowable network. However, there are occasions where the connections between links are not exactly in the correct geographical location. There should be no redundancy of lines or nodes in the database. Initial Quality Control checks found no obvious under- or overshoots. The database, however, is geographically accurate, at the 1:100,000 scale. The ownership/trackage attributes were generated by conflating the Federal Railroad Administration's 1:2,000,000 and the 1:100,000 TIGER/Line databases to the enhanced 1:100,000 DLG database. Additionally, the dataset was "clipped" to the southern and eastern states with ESRI ArcMap 8.2.
The following steps were performed by ESRI: Extracted data set from the National Rail Network 1:100,000. Converted to North American Datum of 1983 (NAD83). Created ArcGIS layer file (.lyr). Created ArcView legend file (.avl). Created projection file (.prj). Ran ArcView Avenue request ExportClean, and created spatial indices.

The positional accuracy can be stated as being that associated with a 1;100,000 scale map.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials. This shapefile covers only the south central and the eastern half of the US. NBII-SAIN (ed.) created this file by clipping from from ESRI 2002 rail100k.shp. NBII-SAIN website: (http://sain.nbii.gov/).
No duplicate features are present. The shapefile is exported using Avenue request ExportClean. This request verifies and enforces the correctness of shapes.
