My answer is a bit of both, the line is the oldest form of any type of fixed guideway transit still in operation in the Pacific Northwest, the Alweg Monorail built for the 1962 Worlds Fare. It is a transit mode that has never really seen the light of day on a widespread scale in the United States. The Monorail Society exists to chronicle them since they have made a splash in other cities:
- Seattle Center–(32 photos)
- Along its mile long Guideway–(20 photos)
- Westlake Center–(34 photos)
Enjoy!
