Illinois State Geological SurveyThis 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.]Shapefileark:/77981/gmgsmg7fv35engPublicGeneralized Railroads Illinois {1996}DatasetsIllinois1996American Geographical Society Library – UWM Libraries
