CTA Blue Line - History

History

The most vintage components of the Blue Line began as part of the Metropolitan West Side Elevated Railroad in 1895. The first section to be built by this company extended west in the vicinity of Van Buren Street from an independent terminal at Canal and Jackson Streets to Marshfield Avenue, and thence northward in the vicinity of Paulina Street to Damen and Milwaukee Avenues. Service on this section was started May 6, 1895. The structure was completed from Damen Avenue to Logan Square on May 25, 1895.

The next stage in the development of the West Side 'L' came on June 19, 1895, when the Garfield Park Branch was added, extending west in the vicinity of Van Buren Street and Harrison Street from Marshfield Avenue to Cicero Avenue. An extension of service over the tracks of the Aurora, Elgin and Chicago Railroad to a new terminal at Forest Park was established on March 11, 1905. A subsequent extension to Westchester opened on October 1, 1926. (Service on the Westchester extension was discontinued by the CTA on December 9, 1951.)

Another branch line was added to the rapidly growing Metropolitan System on July 29, 1895, when trains began operating over the Humboldt Park Branch, paralleling North Avenue from Damen Avenue to a terminal at Lawndale Avenue. (The route was discontinued on May 3, 1952.) This was followed by still another addition when the Douglas Park Branch was placed in operation as far south as 18th Street on April 28, 1896.

As the southwest area of the city developed, the Douglas Park Branch was extended from 18th Street to Western Avenue in September 1896; to Pulaski Road in June, 1902; to Cicero Avenue in December 1907; to Central Avenue in August, 1912; to 62nd Avenue in August, 1915, and to Oak Park Avenue in Berwyn on March 16, 1924. The present west terminal of the Douglas Branch is 54th Avenue, Cicero.

The Metropolitan West Side Elevated began service around the Union Loop on October 11, 1897, and a rush period stub terminal at Wells Street was added October 3, 1904. For much of the early 20th century and through the 1940s, service on the West Side Elevated lines went unchanged until the Chicago Transit Authority took control of Chicago's Rapid Transit System in October, 1947, initiating a series of massive service curtailments and station closings (that would last until the 1980s).

On February 25, 1951, Chicago's second subway route (#2), Milwaukee-Dearborn, was placed in operation by CTA, connecting the Milwaukee Avenue elevated route (formerly Logan Square) with the Central Business District on a fast, efficient and more direct routing through the heart of the city. With opening of the Dearborn Subway, the old elevated alignment between Evergreen and Marshfield Avenues was therefore closed and used only for moving out-of-service rail cars. The north section of this connection between Evergreen Avenue and Lake Street was subsequently demolished in 1960s, leaving the Lake Street Branch-to-Douglas Branch section or the "Paulina Connector" still in existence.

The Garfield Park elevated was replaced by the Congress route on June 22, 1958, pioneering the world's first use of rail rapid transit and a multi-lane automobile expressway in the same grade-separated right-of-way. (Pacific Electric Railway "Red Car" tracks ran in the median of the Cahuenga Parkway in Los Angeles from 1944 until its expansion into the Hollywood Freeway in 1952, but the Pacific Electric service was an interurban streetcar rather than true rapid transit.) The new line connected with the Milwaukee-Dearborn Subway at the Chicago River and extended westward to Des Plaines Avenue, Forest Park. An incline connection en route permitted Douglas trains to operate through the subway as well combining the Logan Square, Garfield Park (now Congress), and Douglas routes into the second through service in Chicago, the West-Northwest route.

A five-mile (8 km) extension of the route via the short subway connection and the Kennedy Expressway median between Logan Square and Jefferson Park was added on February 1, 1970. It was also built by the City of Chicago using federal monies. From Logan Square, trains veers off of the old elevated structure and enters the subway under Milwaukee and Kedzie Avenues to a portal just south of Addison Street, then continues northwest in the median of the Kennedy Expressway to the temporary terminal at Jefferson Park. In March 1980, construction began on the O'Hare Airport extension of the Kennedy route between Jefferson Park and the airport. The first section between Jefferson Park and Rosemont was placed in service on February 27, 1983, and the final section to O'Hare International Airport on September 3, 1984.

In 1993, the Chicago Transit Authority adopted a color-coded naming system to the rapid transit system, and the West-Northwest route (OHare-Congress/Douglas) became the Blue Line. On April 26, 1998, the Douglas Branch lost its overnight (owl) and weekend service and began operating between 4 a.m. (04:00) and 1 a.m. (01:00) on weekdays only as a result of funding shortages requiring CTA cut services. Congress (Forest Park) service was effectively doubled through much of the day since service frequency from O'Hare required shorter headways than what would have been left.

One reason for the Douglas Branch reduction in service was due to its low ridership, badly deteriorated condition, and funding problems, while many residents in the communities it runs through had claimed that it was just another attempt by the CTA to deter transit service on the West Side.

In September 2001, the CTA began a historic reconstruction of the Douglas Branch to repair its aging infrastructure. The work was officially completed on January 5, 2005 with new elevated structures, track, stations, new communication networks and an upgraded traction power system along the route. On January 1, 2005, weekend service was restored.

On July 11, 2006, a rear derailment caused a smokey fire in the Blue Line's Milwaukee-Dearborn Subway. There were injuries from smoke inhalation, but no fatalities. The comparatively minor incident prompted heavy news coverage and a temporary stoppage of Chicago subway service because it occurred hours after train bombings in Mumbai earlier the same day.
