The North/South Line (NS Line) is one of two routes forming the Portland Streetcar system in Portland, Oregon, United States. The route, operated by Portland Streetcar Inc. (PSI) and TriMet, connects the Nob Hill District to the South Waterfront. Opened over its first section in 2001, it was the initial line of the Portland Streetcar system and was the first new streetcar line in the United States since World War II to use modern vehicles. It was given the name North/South Line (abbreviated as NS Line) in September 2012, with the opening of the system's second line (the Central Loop, or CL Line), having previously had no distinct route name.〔''Tramways & Urban Transit'', July 2012, p. 276. UK: LRTA Publishing.〕 ==History== The first section of the North/South line utilized a fleet of five vehicles〔(【引用サイトリンク】url=http://www.portlandstreetcar.org/node/33 )〕 on a 〔 route commencing at Portland State University, running north through the Pearl District and then west to NW 23rd Avenue, in the Nob Hill neighborhood, to the Legacy Good Samaritan Medical Center, and then returning to Portland State University via parallel streets. Although its one-way length was 2.4 miles, PSI commonly described it as a "5-mile loop", because it followed separate streets – one or two blocks apart – over its entire length.〔 This first phase of the North/South line cost $57 million to build, most of which was received from local sources. Only $5 million came from the federal government for the construction. It opened on July 20, 2001.〔〔 In January 2004, construction began to extend the line south of Portland State University to RiverPlace. The extension cost $16 million〔 and opened for service on March 11, 2005.〔 This section includes a short length of two-way single-track operation, about 100 yards (91 m) in length, along Montgomery Street and 4th Avenue, which includes signals for the streetcars to ensure that only one direction is in use at any given time. It also includes the steepest grade on the system, 8.75% in the block of Harrison Street between 1st and 2nd Avenues.〔''Tramways & Urban Transit'', August 2013, p. 352. UK: LRTA Publishing.〕 Another extension, of 0.42 mi (0.68 km) south to the lower terminus of the Portland Aerial Tram at SW Gibbs Street, in the South Waterfront District, opened on temporary tracks on October 20, 2006, all on its own right-of-way formerly used by the Willamette Shore Trolley and initially also single-track. In November 2011, the streetcar line began using new double track on a realigned section of Moody Avenue.〔 On August 17, 2007, an extension of the line south of Gibbs Street to SW Lowell and Bond opened to better serve the South Waterfront district.〔 This 0.46-mile (0.74 km) extension is a 10-block loop, from SW Moody and Gibbs proceeding south on Moody Avenue, east on Lowell Street and north on Bond Avenue to OHSU Commons at Gibbs, which stop is also directly adjacent to the entrance to the Portland Aerial Tram, linking the stop to Oregon Health & Science University (OHSU) atop Marquam Hill. This final extension of the line cost $14.45 million.〔 The extensions that opened in 2005, 2006 and 2007 increased the one-way length of the line to its current . The stops at OHSU Commons and Gibbs Street received a connection to the Lair Hill neighborhood that was otherwise cut off by Interstate 5 upon the opening of the Gibbs Street Pedestrian Bridge in July 2012. Until 2012, the north-south streetcar line had no route name, being referred to only as the Portland Streetcar line, because it was the only line in the PS system. However, with the opening of the system's second line, in September 2012, the original line was designated as the North/South Line (abbreviated as NS Line) to distinguish it from the new Central Loop line (or CL Line).〔〔 In 2015, the NS Line's SW Moody & Meade station will be across the street from the end of the Tilikum Crossing bridge, which will connect the North/South line with the Central Loop line, MAX Orange Line, and additional TriMet bus services. 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「NS Line (Portland Streetcar)」の詳細全文を読む スポンサード リンク
