caption_attribution_description: Portland, Oregon: An ad-free MAX train composed of a Type 2 car (low-floor design) and a Type 1 car (older, high-floor design) southbound on S.W. 5th Avenue at Mill Street in Downtown Portland (which TriMet refers to as the City Center, contrary to common local usage). The specific cars shown are 223 + 103. TriMet's Type 2 cars are a series of 52 Siemens SD660 LRVs (light rail vehicles) built over the period 1996–2000, which were the first low-floor LRVs in North America, and its Type 1 cars are a series of 26 LRVs built by Bombardier over the period 1983–86.
context_page_description: The MAX Yellow Line is a light rail service in Portland, Oregon, United States, operated by TriMet as part of the MAX Light Rail system. It connects North Portland to Portland City Center and Portland State University. The line originates at Portland Expo Center in the north and runs south to the Rose Quarter along a 5.8-mile segment referred to as the Interstate MAX. From there, it crosses the Willamette River into downtown Portland and operates as a northbound-only service of the Portland Transit Mall on 6th Avenue. The line serves 17 stops between the Expo Center and PSU South/Southwest 6th and College stations; of these, seven stops occupy the median of North Interstate Avenue, giving that segment its name. The Yellow Line runs for approximately 21 hours daily with a minimum headway of 15 minutes during most of the day.
  Following years of failed attempts to construct the South/North Line between Clackamas County and Clark County, Washington, Portland business leaders and local residents persuaded TriMet to build a light rail extension to North Portland in 1999.

It connects North Portland to Portland City Center and Portland State University (PSU). The line originates at Portland Expo Center in the north and runs south to the Rose Quarter along a 5.8-mile (9.3 km) segment referred to as the Interstate MAX. From there, it crosses the Willamette River into downtown Portland and operates as a northbound-only service of the Portland Transit Mall on 6th Avenue. The line serves 17 stops between the Expo Center and PSU South/Southwest 6th and College stations; of these, seven stops occupy the median of North Interstate Avenue, giving that segment its name.

  Following years of failed attempts to construct the South/North Line between Clackamas County and Clark County, Washington, Portland business leaders and local residents persuaded TriMet to build a light rail extension to North Portland in 1999. As a source of funding, the city created an urban renewal area, which has since partly been blamed for gentrifying historically black inner-city neighborhoods. The line began construction in 2001 and opened on May 1, 2004, four months ahead of schedule. From 2004 to 2009, the Yellow Line ran between Expo Center station in North Portland and the Library and Galleria stations in downtown Portland, sharing tracks within downtown with the Blue Line and the Red Line. In 2009, TriMet rerouted it to the newly rebuilt Portland Transit Mall.
  Since 2015, the Yellow Line has operated as a northbound through service of the Orange Line from PSU South/Southwest 6th and College station, sharing its transit mall alignment on 6th Avenue with the Green Line. Conversely, most southbound Yellow Line trains, which had served the other half of the mall on 5th Avenue from 2009 to 2015, through operate into the Orange Line from Union Station/Northwest 5th & Glisan Street station and terminate at Southeast Park Avenue station in Milwaukie. As of September 2019, the Yellow Line is the fourth-busiest service in the MAX system, carrying an average of 12,960 riders each weekday.
