MAX Red Line
Light rail line serving Beaverton, Portland, and Portland International Airport
The MAX Red Line is a light rail line serving the Portland metropolitan area in the U.S. state of Oregon. Operated by TriMet as part of MAX Light Rail, it is an airport rail link connecting Hillsboro, Beaverton, Portland City Center, and Northeast Portland to Portland International Airport. The Red Line serves 36 stations; it shares its route with the Blue Line from Hillsboro Airport/Fairgrounds station to Gateway Transit Center and then branches off to Portland Airport station. Service runs for 22 hours per day with headways of up to 15 minutes. The Red Line carried an average 17,390 passengers per weekday in September 2024, the second busiest after the Blue Line.
Plans for light rail service to Portland International Airport surfaced in the 1980s, and efforts were accelerated during the airport's expansion in the 1990s. The Airport MAX project was conceived from an unsolicited proposal by Bechtel in 1997, and it was designed and built under a public–private partnership between a consortium of Bechtel and Trammell Crow, the Port of Portland, and local governments. Construction of the four-station, 5.5-mile (8.9 km) branch line began in 1999 and was completed in under two years due to the use of local and private financing and existing public right-of-way.
The Red Line began operating between the airport and downtown Portland on September 10, 2001. It was extended west along existing MAX tracks to Beaverton Transit Center in 2003.

Why this record matters
The phrase “light rail line serving Beaverton, Portland, and Portland International Airport” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 3, 2026.

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
