Purple Line (CTA) — Evanston branch of the Chicago 'L'

The Purple Line, often called the Evanston Line, is a CTA rapid transit route linking Linden in Wilmette with Howard on Chicago's North Side; it also runs express to the Loop during weekday peak periods.

Overview

The Purple Line is a north‑side route of the Chicago Transit Authority's elevated rapid transit network, commonly referred to as the Evanston Line. Its core segment runs between Linden Avenue in Wilmette and Howard Street on Chicago's north side, a distance of about 3.9 miles (6.3 km). The line carries local service within the northern suburbs and provides additional downtown express trains during weekday peak periods.

Route and characteristics

The line serves a corridor that includes residential neighborhoods, commercial strips and institutional destinations. Stations on the Purple Line connect riders with local buses and at Howard provide transfers to the CTA Red Line and other services. Trains on the Purple Line use CTA rapid transit rolling stock compatible with the rest of the "L" network and operate on standard gauge track with third‑rail electrification.

History and development

The Evanston corridor developed as part of late 19th and early 20th century rapid transit growth in the Chicago region. It began as suburban and elevated railway extensions that were later integrated into the CTA system and given the color designation used today. Over time the line and its stations have undergone rehabilitation and periodic modernization efforts to maintain service, accessibility and safety for commuters.

Operations and ridership

Daily patterns typically include local shuttle service between Linden and Howard throughout most of the day and additional express runs to downtown Chicago during weekday rush hours. These express trains run through the North Side to the Loop, providing a faster option for commuters. The Purple Line carries a modest ridership compared with some other CTA routes; for example, average weekday boardings were recorded at 10,187 in 2016.

Importance and distinctions

The Purple Line links suburban communities such as Wilmette and Evanston with Chicago's rapid transit network.
Howard station is a major transfer point, connecting Purple Line riders to the Chicago Transit Authority Red Line and multiple surface routes.
The line's express service during peak periods distinguishes it from some purely local branches, offering a direct commute option to the downtown area.

For official schedules, service advisories and system maps consult the CTA publications and websites maintained by the transit agency. Historical overviews and technical descriptions of the Chicago "L" network provide additional context on how the Evanston branch fits into the region's rail transit legacy. See material from transit authorities and local transportation studies for current project plans and ridership data. Chicago "L" system information and regional resources are useful starting points.

Additional resources and archival summaries can be found through municipal transportation departments and local historical societies that document the development of commuter rail and elevated transit in the Chicago metropolitan area. Evanston-focused sources and community planning documents also describe the Purple Line's role in local mobility and development.

Official station details, fare information and connections are periodically updated by the CTA; riders should consult current schedules before travel. CTA notices and planning pages contain the latest operational changes and modernization initiatives.
