RAIL_SYSTEM_INDOT_IN is a line shapefile that shows the 2006 rail system of Indiana. It is derived from data provided by personnel of the Indiana Department of Transportation (INDOT). Recent 2006 edits to this data set include removal of abandoned rail lines and inclusion of ownership changes. New attribute fields have been added by INDOT personnel to include items such as contact names, phone numbers, mailing addresses, and freight classifications. The following is excerpted from the metadata provided by INDOT, Office of Railroads, for the source shapefile named RAILROADS_TRAFFIC_2006.SHP: "RAILROADS_TRAFFIC_2006.SHP is a line shapefile delineating the railroad tracks within the State of Indiana. The dataset was generated at a scale of 1:1200."
