As of February 2013, the branch serves an average of 27,217 passengers each weekday. It serves the Near West Side, East Garfield Park, West Garfield Park, and Austin neighborhoods of Chicago, as well as the suburbs Oak Park and Forest Park. It owes its name to Lake Street, the street that the branch overlooks for before continuing its route straight west, adjacent to South Boulevard, towards the terminus at Harlem/Lake. The branch runs from 3:50 am to 1:25 am on weekdays, 4:50 am to 1:25 am on Saturdays and Sundays/Holidays. ==History== The Lake Street Elevated began regular passenger service on November 6, 1893, from its eastern terminal at Madison Street and Market Street to California Avenue. On November 24, 1893 service on the line was extended to Homan Avenue. In March 1894, service on the line was extended to 48th Avenue (now known as Cicero Avenue) and on April 29, 1894, service was extended to 52nd Avenue (now known as Laramie Avenue), which at the time was the city limits of Chicago. When the completed Loop opened October 3, 1897, the Lake Street Elevated became the first line to utilize the entire quadrangle.〔(Loop Elevated ) Chicago 'L'.org. Accessed August 19, 2013〕 In 1898, an agreement was reached with Cicero Township to extend the Lake Street Elevated beyond the Chicago city limits into what at the time was Cicero Township. This agreement allowed for the extension of the Lake Street Elevated along South Boulevard, as well as the creation of the Randolph Street and Cuyler Avenue branches. On January 25, 1901, service was extended to Wisconsin Avenue (later called Marion), and on May 20, 1910, service was extended to its west-most terminal approximately two blocks west of Harlem Avenue in Forest Park. In April 1948, the Lake Street Elevated was the first line of the 'L' system to use the Skip-Stop A/B service. Upon the implementation of Skip-Stop A/B service ten stations on the Lake Street Elevated were closed, as was the Market Street Stub, and all trains were routed through the Loop. This new system decreased the travel time of 24-35 minutes, which was considered by the CTA and its users to be a great success. In 1962, of surface level track in Chicago's Austin neighborhood and Oak Park, Illinois were replaced by elevated tracks which run on Chicago & North Western Railroad's track embankment. Central, Austin, Ridgeland, Oak Park had new stations built and a new terminus opened at Harlem/Lake, replacing the station at Marion and the old Forest Park terminus. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Street Elevated (CTA)」の詳細全文を読む スポンサード リンク
