Railway Network (1:2,000,000 base scale) (Node) - Data Dictionary
Abstract: The Rail Network is a comprehensive data set of the nation's railway system at the 1:2,000,000 scale. The data set covers the 48 contiguous States plus the District of Columbia.
Purpose: The database provides location and attribute information for use in national and regional network analysis applications.
Supplemental Information: At the time of publishing the CD significant updates to the layer were underway. Please check http://gis.fra.dot.gov for the latest version of the dataset.
The National Rail Network: 1:2,000,000 (line) contains 1 polyline feature (FRAID 8298) that is defined by more than 500 shape points. This feature will not import correctly into the workstation version of ArcInfo, which has a 500 shapepoint limit. When importing into the workstation version of ArcInfo, this feature will be automatically split into 2 features. As part of this process, attributes are simply duplicated on the split features. Because of this, an additonal node is added. The additional node will have incomplete attribution.
