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_ccuracy:

  Attribute_Accuracy_Report: The railroad ownership field is complete to

     approximately mid-2000.

 

     The FRA reports the following fields as complete:

         Railroad Ownership

         State/County (FIPS5)

         State Code

         FRA Regions

         Link Type (subject to change)

         Passenger Flag

         Abandoned Flag

         Billing Railroads

         Railroad Class

     The FRA reports the following fields as incomplete:

         Signals

         Density Code

         Military Flag - applied only in some states

         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 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.

 

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.
