The Orange Line, is a rapid transit line in Chicago, Illinois run by the Chicago Transit Authority as part of the 'L' system. It is approximately long and runs at grade and elevated on existing railroad embankments and new concrete and steel structures from Midway International Airport, the Southwest Side and downtown Chicago. In September 2012, the average weekday boardings on the Orange Line were 63,037. The Orange Line operates between Midway Airport and the Loop, weekdays from 4:00 a.m. to 1:25 a.m., and Saturdays and Sundays from 4:30 a.m. to 1:25 a.m. == Route == From the Midway Terminal, the Orange Line begins in an open cut near Midway Airport and then rises to elevated structure at 55th Street and continues northeast towards the city on railroad right-of-way. At Lawndale Avenue the line turns east along Conrail right-of-way at 49th Street to a point east of Western Boulevard, then curves north and northwest on embankment structure along CSX and Conrail right-of-way to Western Boulevard and Pershing Road. From here, the line rises on elevated structure again and makes a curve to cross Archer Avenue, the Conrail tracks and Western Boulevard before descending onto Illinois Central (ex-Gulf, Mobile and Ohio) Railroad right-of-way immediately east of Western Boulevard. Entering the IC right-of-way, the line again changes from elevated structure to surface level. The line continues on surface level to Ashland Avenue where it crosses the bridge of the South Branch of the Chicago River. At this point, the line enters the joint Illinois Central and Atchison, Topeka and Santa Fe Railroad right-of-way continuing on embankment to Canal Street. There the line again transitions to the elevated structure to bridge Canal Street, Cermak Road and the Chicago & Western Indiana Railroad tracks then curves east to run along the south side of 18th Street, crossing over the Red Line and Metra's Rock Island District tracks near Wentworth Avenue, before joining the other CTA 'L' lines immediately east of State Street, with the northbound track over the double track South Side Elevated. The ballasted track ends and the timber deck begins here. Orange Line trains share the tracks with the Green Line operating from the connection at 17th Street to the Loop. Orange Line trains operate around the Loop clockwise on the Inner Loop track via Van Buren-Wells-Lake-Wabash serving all Loop stations before returning to Midway Airport. Along the Orange Line's main route there are seven stations. An eighth station is located at Roosevelt/Wabash on the old South Side 'L' which Orange Line trains share with Green Line trains. A passenger tunnel connects this station with the Roosevelt/State subway station on the Red Line. A downtown superstation has been proposed to provide express service from the Loop to O'Hare and Midway, via the Orange and Blue Lines. The station would provide services such as baggage check. The downtown terminal is under construction, but the express tracks required for the Airport Express trains have yet to be funded. 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「Orange Line (CTA)」の詳細全文を読む スポンサード リンク
