The Green Line (Lake-Englewood & Lake-Jackson Park Services) is part of the CTA rapid transit system known as the Chicago 'L'. It is the only completely elevated route in the 'L' system. ^[1] It utilizes the system's oldest segments (dating back to 1892), extending 20.8 miles with 29 stops between Forest Park and Oak Park (Harlem/Lake), through Chicago's Loop, to the South Side and Englewood (Ashland/63rd) and Woodlawn (Cottage Grove/63rd).

The Lake Street Elevated bridge over the Chicago River at night.

Beginning at the yard and inspection facilities in Forest Park, the Green Line runs east through Oak Park towards the city on an embankment parallel to Metra's Union Pacific West Line tracks from the Harlem Avenue terminal (7200 W. - 400 N.), on the border of Oak Park and River Forest, to a point just west of Laramie Avenue. Here the Green Line tracks leaves the railroad embankment and continues east on a steel elevated structure directly above Lake Street, a major east-west thoroughfare. The 'L' bridges a couple of railroad tracks before entering downtown Chicago at Clinton Street. East of Clinton Street, the route bridges Metra's Union Pacific railroad tracks (which terminate just south of here at Ogilvie Transportation Center) and the Chicago River before joining the Union Loop 'L' tracks at Wells Street.

In downtown Chicago, the Green Line operates over the famous Union Loop 'L' structure along with Brown Line (Ravenswood), Orange Line (Midway), Pink Line (Douglas), and Purple Line (Evanston Express during Weekday rush hours only) trains. However, Green Line trains operate both ways over the Lake Street and Wabash Avenue sides only, and does not use the Wells Street and Van Buren Street legs of the Loop.

Leaving the Loop, the route heads south along Wabash Avenue and follows an "S" curve (which was realigned in 2002) to the west and south now following the alley between Wabash Avenue and State Street to 40th Street. This is the oldest section (3.8 miles) of Chicago's 'L'-Subway system. On this segment, the Green Line shares tracks with the Orange Line between the Loop and 17th Street. Passengers can transfer between the two lines at Roosevelt/Wabash station. The only other station on this section is at 35-Bronzeville-IIT (which is 2.5 miles south of Roosevelt/Wabash) adjacent the Illinois Institute of Technology campus and the Chicago Police Department Headquarters. At 40th Street, the route turns east to Indiana station, then turns south between Calumet and Prairie Avenues to the Garfield station and continues south to 59th Street where the route splits into two branches -- the Englewood (Ashland/63rd) Branch and the Jackson Park (East 63rd) Branch.

The Englewood Branch continues south and west following 59th Street, Princeton Avenue and 63rd Street to the Ashland Avenue terminal (1600 W. - 6300 S.) in West Englewood. The yard and inspection shop lie to the south between the old Racine Avenue station and the Ashland/63rd terminal. The 'L' tracks continues west to a stub end at Hermitage Avenue, a provision for a future extension of the route westward, however, those plans were cancelled in the late 1970's. Prior to 1992, the Englewood Branch had three additional stops at Wentworth, Harvard and Racine, but have been since closed due to service curtailments by the CTA. Halsted/63rd is the only remaining intermediate stop on the 3.1 mile route.

East/63-Cottage Grove Station

The Jackson Park Branch continues south from the mainline between Calumet and Prairie Avenues, passing the old yard and inspection facilities at 61st Street in Washington Park. South of here, the route curves east over 63rd Street and follows it to the current (and temporary) terminal at Cottage Grove/63rd (800 E. - 6300 S.). Prior to 1994, the Jackson Park Branch of the Green Line once terminated at University/63rd, and before that, at Stony Island/63rd from 1893 to 1982.

Currently, the Green Line is operated only with 2400-Series rail cars, which were built by Boeing-Vertol between 1976 and 1978. These cars are scheduled for retirement after 2010. Trains generally operate at 10 to 12 minute headways during much of the day (about 20 to 25 minutes on the Englewood and Woodlawn branches), with 4 to 6 car trains. There is no overnight service along the Green Line.

The Green Line operates over the two oldest sections of the Chicago 'L'-Subway rapid transit system. The South Side section started operation in 1892 when Chicago was preparing for the World's Columbian Exposition of 1893 in Jackson Park. The initial section being built to provide service between downtown Chicago and the exposition site. This first section of Chicago's new "High Line" between Wabash Avenue and State Street went into service on June 6, 1892. It extended from Congress Street only as far south as 39th Street (Pershing Road). At that time a large part of the south side was little more than prairie, but by May 1, 1893, when the pioneer 'L' line was completed to Jackson Park, construction of homes, apartment buildings and commercial properties was booming in the area.

Continued expansion of the area development was reflected in construction of the Englewood, Normal Park, Kenwood and Stock Yard branches of the South Side 'L' between 1905 and 1908. Of these, only the Englewood and Jackson Park branches remain: because of insufficient patronage, the Normal Park, Stock Yards and Kenwood branches were closed in the 1950s.

The Lake Street Elevated was Chicago's second rapid transit line, it began operation from Madison and Market streets to Lake Street and California Avenue on November 6, 1893. The line was gradually extended westward to Laramie Avenue on April 29, 1894; to Austin Avenue on April 15, 1899; to Wisconsin Avenue, Oak Park using street railway trackage on May 15, 1899 (closed in 1902), and to Marengo Avenue, Forest Park, on May 14, 1910.

The construction of the Lake Street Elevated led to a political quarrel in suburban Cicero Township, which at the time included Oak Park and Austin. In 1898, Austinites, having a majority on Cicero's town council, used political influence to allow the extension of the Lake Street line from the city border at Laramie Avenue (then called 52nd Avenue) into their community. This infuriated other Cicero Township residents, who retaliated the following year by holding a joint election to force Austin's annexation to the City of Chicago. Much to the dismay of local residents, this effort succeeded, and Austin became part of Chicago in 1899. A century later, Oak Park commuters, who had come to depend on the service, were among the most vocal critics of the Green Line's closure for rehabilitation.

Between 1913 and 1993, the Englewood/Jackson Park branches was part of the North-South Route in various service configurations operating from the north side through the Loop, and to the south side. On October 17, 1943, the Englewood and Jackson Park services were rerouted into the Clybourn-Division-State Subway to provide improved crosstown access through the heart of city and to alleviate congestion on the over-crowded Union Loop Elevated. On July 31, 1949, during the North-South rapid transit service revision by the CTA, the Howard-Englewood/Jackson Park route was created, operating via the State Street Subway.

On May 6, 1969, the Englewood branch was extended to the present South terminal at Ashland/63rd. In 1982, the Jackson Park branch was shortened to University Avenue because of structural deterioration at the Dorchester Bridge which carried the route across the Illinois Central Railroad and the former Stony Island/63rd terminal was closed March 4, 1982.

The Lake Street 'L' would remain largely unchanged until 1948, when a number of its historic passenger stations were closed and subsequently demolished in an attempt to promote the "A" and "B" skip-stop express train service (discontinued in 1994). On October 28, 1962, the western two and one-half mile section of the line which operated at street level was elevated along the Chicago and Northwestern Railroad right-of-way opening new above-ground stops at Central, Austin, Ridgeland, Oak Park and Harlem/Lake, Forest Park. On September 28, 1969, the Lake Street line was combined with the new Dan Ryan Line to form the West-South Route, operating from Forest Park through downtown via the Union Loop 'L' to 95th/Dan Ryan. The Lake-Dan Ryan routing was to fulfill the service implementation outlined in the 1968 Chicago Central Area Transit Plan. However, when that controversial subway project was cancelled in 1979, Lake-Dan Ryan service remained, and lasted for nearly 24 years.

On February 21, 1993, the south side sections of the North-South and West-South routes were "switched" south of Roosevelt Road, creating the present Red Line (Howard-Dan Ryan) and the Green Line (Lake-Englewood/Jackson Park)

On January 9, 1994 the Green Line was closed for more than two years for the largest transit rehabilitation project in the city's history. It was reopened May 12, 1996 with much of the renewal work completed with the exception of a few stations. Several stations were closed indefinitely following the rehabilitation which angered many commuters who depend on the Green Line. In September 1997, after political pressure brought on by community organizations, the Jackson Park branch was shortened again from University Avenue to Cottage Grove/63rd (East 63rd) after previous attempts by the City, CTA and other agencies to extend the route eastward to Dorchester Avenue, immediately west of the Illinois Central Railroad.

On April 26, 1998, the Green Line, like the Purple Line and the Douglas branch of the Blue Line lost its 24 hour service due to budget shortfalls and operates only between the hours of 4 a.m. and 1 a.m weekdays. The Green Line runs 6 a.m. Saturdays and 6:30 a.m. on Sundays

The Green Line provides access to, among other destinations, the Garfield Park Conservatory (Conservatory-Central Park Drive), James R. Thompson Center, Richard J. Daley Center and City Hall-Cook County Building (Clark/Lake), Millennium Park (Randolph/Wabash and Madison/Wabash), the Art Institute of Chicago (Adams/Wabash), the Auditorium Building of Roosevelt University, the Museum Campus and Soldier Field (Roosevelt/Wabash), the Illinois Institute of Technology and U.S. Cellular Field (White Sox Park) (35th-Bronzeville-IIT), the University of Chicago (Garfield) and when completed in 2010, the new Kennedy-King College (Halsted/63rd). The Clinton/Lake and Randolph/Wabash stops are useful for reaching Metra and South Shore Line trains at the Ogilvie Transportation Center and Randolph Street station.
