Seattle Center Monorail

The Seattle Center Monorail is an elevated straddle-beam monorail line in Seattle, Washington, United States. The 0.9-mile monorail runs along 5th Avenue between Seattle Center and Westlake Center in Downtown Seattle, making no intermediate stops. The monorail is a major tourist attraction but also operates as a regular public transit service with trains every ten minutes running for up to 16 hours per day. It was constructed in eight months at a cost of $4.2 million for the 1962 Century 21 Exposition, a world's fair hosted at Seattle Center. The monorail underwent major renovations in 1988 after the southern terminal was moved from its location over Pine Street to inside the Westlake Center shopping mall.

The system retains its original fleet of two Alweg trains from the world's fair; each carries up to 450 people. It is owned by the city government, which designated the tracks and trains as a historic landmark in 2003.
