Abstract
This line data layer represents generalized railroads for Illinois in 1996. The dataset was originally created by the Illinois State Geological Survey in 1996.[This arc coverage consists of line features that represent the general railroad infrastructure of Illinois. Most of these rail lines were active as of 1996. This information was derived from the US Geological Survey 1:100,000 Digital Line Graph files (transportation layer) and from the Illinois Railroad Map, published by the Illinois Department of Transportation (1994). This is not a complete representation of rail lines in Illinois. Several features are not included, such as (1) spur lines and rail yards in major metropolitan areas, other municipalities and industrial locations, (2) some lines less than 1-2 miles in length, and (3) ancillary tracks at junctions and other areas. The state boundary is not included in this data set.Arc segments are annotated with abbreviated railway designations. However, it is not known when these annotations were last updated and verified. It is suspected that several annotations may no longer properly reflect rail ownership.]
Purpose
This layer is intended for reference and mapping purposes and may be used for basic applications such as viewing, querying, and map output production or to provide a basemap to support graphical overlays and analysis with other spatial data. [This data set is primarily intended as a cartographic layer. The information can be used to display the general location of railroads on regional or statewide maps. The features included in this coverage were selected to show the major railroad network of Illinois at a scale of 1:500,000, without cluttering the map or impeding the clear display of other map features (such as roads, municipalities, and other infrastructure.) These data are appropriate for use in local and regional thematic analysis at scales of 1:100,000 or smaller.]
