Chicago Transit Authority yellow line train at Dempster Street terminal. January 2004.

This photograph was taken on a late January afternoon in 2004. This was the last year of "Overhead Wire Operations" on the CTA Yellow line, formerly known as "The Skokie Swift". This shuttle El line opened in 1964 and uses part of the former Chicago North Shore and Milwaukee electric railroad's -Skokie Valley Route right of way. For many years the village of Skokie
Illinois had an ordinance against Third Rail operations for fear of Electrocution Accidents, so from 1964 until 2004 -the segment from East Prairie Road to Dempster Street ran on overhead catenary wire. The cars pantographs would raise and lower at speed. In 2004, the ordinance was Repealed and the entire line is now 100% Third Rail operated.
