ITEM                  ITEM DESCRIPTION
Shape		      Data attribute inherent to the ESRI shapefile format,
		      which defines the data as a point, polyline, or polygon.

Version               The VERSION is a 2-digit number that will be    
 		      incremented for all records in the database 
		      whenever a new release is distributed. In this 
                      release, the value is "02".                       

Revision              The REVISION is a 2-digit number that will be 
                      incremented individually for each record whenever  
                      a change is made to one of the fields, in 
                      this release the value will be no greater than  

Moddate               The MODDATE (or modification date) indicates when 
                      each record in the database was last changed.  As 
                      changes are made to record, the modification 
                      date is entered in the format 'yyyymmdd'.

Railroad              Identification of the railroad owner as
                      provided in the original 1:100,000 scale data. 
                      The field may also contain the value "FRA ADDED" 
                      where the link was not contained in the
                      original data.                     
Abdyr                 Year abandoned, if known -incomplete inthis 
Descript              FGDL added item based on Railroad


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:
         Density Code
         Military Flag - applied only in some states
         Abandonment Year
Also, the Federal Railway Administration (FHA) 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.
The dataset provides location and attribute information for use in national and 
regional cartographic and network analysis applications.

A note concerning data scale:
Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling purposes. Please be sure
you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county
level. 1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.

1:250000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered
suspect. Make sure you are familiar with your data before using it for
projects or analyses. Every effort has been made to supply the user with
data documentation. For additional information, see the References section
and the Data Source Contact section of this documentation. For more
information regarding scale and accuracy, see our web pages at:



-Reprojected data to FGDL Albers HPGN (See "Map Projection Parameters" below)
-Upcased all character records
-Added Descipt item based on Railroad


Bureau of Transportation Statistics


In 2001, the Geoplan Center downloaded this data in shapefile format from the 
Bureau of Transportation Statistics website (
When received, the data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980,
Units: Decimal degrees. The data was reprojected to FGDL Albers HPGN, the "descript" 
item was added based on the existing items 'railroad", and lowercase characters 
within the attribute table were upcased.
