CTA Rail Lines

Dataset:CTA Rail Lines
Source:CTA, RTA
Data Vintage:June 2006
Update Frequency:As needed
Description:This line file contains the locations of Chicago Transit Authority (CTA) rail lines. It was created by staff of the Regional Transportation Authority in the Winter of 2001, based upon a comprehensive edit of the Northeastern Illinois Planning Commission's 1:24,000 scale 1995 CTA Rail Lines and Stations ArcInfo coverage file. The locations of all rail lines were edited based upon September 1999 digital aerial photos. The lines in this file represent the approximate center of the rail corridors with current CTA passenger service; they do not represent individual rail tracks within the same corridor. A corresponding CTA rail station file was also created.
