    Description: 
      Abstract: 
      The Rail Network is a comprehensive database of the nation's railway 
      system at the 1:100,000 scale. The data set covers the 48 contiguous 
      States plus the District of Columbia. 
      Purpose: 
      The data set provides location and partial attribute information for use 
      in national and regional network analysis applications.

  Data_Quality_Information: 
    Attribute_Accuracy: 
      Attribute_Accuracy_Report: 
      The railroad ownership field is complete to approximately mid-2000. The 
      FRA reports the following fields as incomplete: Signals Density Code 
      Military Flag(applied only in some states) and Abandonment Year. Also, the 
      FRA reports that as many nodes as possible have been identified with a 
      name. There are likely more that are not easily identified. Many nodes in 
      the 1:100,000 scale rail network are 'mapped' to a node in the 1:2,000,000 
      scale rail network. Special note concerning trackage rights: In some 
      cases, a 'short line' railroad may operate on its larger railroad 
      connection(s) as its billing railroad. For example, the larger railroad(s) 
      treat traffic originating or terminating on the short line as if it were 
      originating or terminating on its own line; perform the billing, car 
      reporting, and car tracking; then share the revenue with the short line. 
      These trackage rights may exist as four, five, or six in the sequence, 
      while one and two remain empty. 
      Quantitative_Attribute_Accuracy_Assessment: 
        Attribute_Accuracy_Value: unknown 
    Logical_Consistency_Report: 
    The network is not topologically connected. There should be no redundancy of 
    lines or nodes in the data set. The data set is geographically accurate at 
    the 1:100,000 scale 
    Completeness_Report: See Attribute Accuracy Report (above). 
    Positional_Accuracy: 
      Horizontal_Positional_Accuracy: 
        Horizontal_Positional_Accuracy_Report: 
        The horizontal accuracy for these data can be stated as being that 
        associated with data compiled at the 1:100,000 scale.
