The Yellow Line (Skokie Swift Service), is part of the Chicago Transit Authority's Chicago 'L' heavy rail rapid transit system in Chicago, Illinois. The 5.1 mile (8.2 km), non-stop shuttle route runs from the Howard Street Terminal on the northern city limits of Chicago, through the southern part of suburban Evanston, to the Dempster Street Terminal in Skokie, Illinois.
At Howard Street, Yellow Line passengers can transfer to the Purple or Red Lines of the CTA. The Yellow Line is the only CTA line that does not go to Chicago's Loop. It is also unique in that it runs in a below-grade trench for part of its length, although it has no subway component and does not run in an expressway median. It was built using the tracks of the former Chicago North Shore and Milwaukee Railroad's high-speed Skokie Valley Line.
Extending the line to Old Orchard Mall in Skokie has been discussed as well. At one time the line had several intermediate stops in Evanston and Skokie--including one at Oakton--but these stations have long been out of use and have been dismantled.
Travel time along the Skokie Swift-Yellow Line is about eight minutes. Trains operate using Morrison-Knudsen-built 3200-Series rail cars in two-car train consists with 10 to 12 minute headways all day. Service is provided Mondays through Fridays only, between 5am and 10pm, with about 2,800 daily station entrances, and weekend service begins on March 30, 2008.
