Pioneer Square stations (TriMet)

The Pioneer Square stations are a pair of light rail stations in Portland, Oregon, United States, served by TriMet as part of MAX Light Rail. Located at Pioneer Courthouse Square in downtown Portland, the stations are built into the sidewalks of Southwest Yamhill and Morrison streets between Broadway and 6th Avenue. Each station comprises one side platform, and trains traveling eastbound stop at Pioneer Square South station, while trains traveling westbound stop at Pioneer Square North station.

The Pioneer Square stations are among the 27 original stations of the Banfield Light Rail Project, which built the Metropolitan Area Express (MAX), Portland's first light rail line. They opened along with the inaugural service of MAX on September 5, 1986. The stations are served by the Blue Line, which operates between Hatfield Government Center station in Hillsboro and Cleveland Avenue station in Gresham, and the Red Line, which operates between Hillsboro Airport/Fairgrounds station and Portland Airport station. The Yellow Line had served the stations from May 2004 until August 2009 when the line was rerouted to the Portland Transit Mall.

The Pioneer Square stations, along with the Pioneer Courthouse/Southwest 6th and Pioneer Place/Southwest 5th stations located one block east, mark the only transfer point where riders can board any of the five MAX lines.
