context_page_description: MAX Light Rail is a light rail system in Portland, Oregon, United States, that is owned and operated by TriMet. The 59.7-mile network consists of 94 stations served by five color-designated lines. The system, which operates in Oregon's Clackamas, Multnomah, and Washington counties, connects all six sections of Portland; the suburban communities of Beaverton, Clackamas, Gresham, Hillsboro, and Milwaukie; and Portland International Airport to Portland City Center. As of 2018, MAX is the fourth-busiest light rail system in the United States after comparable light rail services in Los Angeles, Boston, and San Francisco. The system had an average daily ridership of 120,900 and nearly 39 million annual riders in 2019. Lines run seven days a week with headways of between 30 minutes off-peak and three minutes during rush hours.
  MAX was among the first second-generation American light rail systems to be built. It was conceived as a result of freeway revolts that took place in Portland in the early 1970s.
context_section_description: The MAX rail network is 59.7 miles (96.1 km) long; TriMet typically rounds this figure up to 60 miles (97 km). It was built in a series of six projects starting with the Banfield—now Eastside—alignment. A portion of the Eastside MAX between 11th Avenue and Gateway Transit Center is now served by the Blue, Green, and Red lines. A section of the Westside MAX between Beaverton Transit Center and 11th Avenue is served by the Blue and Red lines. The Green, Orange, and Yellow lines share the segment that was built as part of the Portland Transit Mall light rail project. The four remaining segments, all of which are located outside the city center, are operated by one service, often making the service and segment synonymous (e.g. Red Line and Airport MAX).
