The Issaquah Valley Trolley is a planned heritage streetcar line in Issaquah, Washington, United States. It is a project of the Issaquah Historical Museums (formerly known as the Issaquah Historical Society), and the trolley carbarn is just north of the Issaquah Depot Museum, located at 50 Rainier Blvd. North. In 2001–02, a demonstration trolley borrowed from Yakima Valley Trolleys was operated along existing, former-freight railroad track to prove the concept that an operating trolley in Issaquah would attract ridership. The project is still under development at this time.
After returning the borrowed trolley to Yakima in May 2002,[1] Issaquah acquired three trolleys of its own: a Milan interurban car, and two narrow gauge trolleys from a failed plan for a trolley line in Aspen, Colorado. Currently, none is operating, as they all require restoration work before they can begin service. However, the museum does have an operational 0-4-0 Plymouth gasoline-mechanical locomotive. The two narrow gauge trolleys are to be "re-gauged" so that they can run on standard gauge railroad track. The trolleys will tow a generator car to supply them with electricity, rather than receiving power from overhead wires. The group hopes to rebuild about a mile of recently removed track on the Lake Sammamish rail-trail, as far as the boat-launch.
