Puget Sound Electric Railway Interurban 523
Interurban 523 is a King County and City of Snoqualmie Landmark. Built by St. Louis Car in 1907 and put into service in 1908. More than a dozen South King County communities were once served by the PSER and car 523. Car 523 is the only known surviving car, and originally served as a combination coach/parlor/observation car. In September 2017, interurban 523 moved from where it had been stored for 20 years in Petaluma, California to the Northwest Railway Museum.
