The first long-distance electric interurban line in the United States, made possible by the hydroelectric plant on the Willamette Falls at Oregon City. The line originally ran down along what would later be the Sellwood city streetcar line, before being rerouted along the waterfront Springwater Division in 1904. The Oregon City line was one of the last traction lines to be abandoned when the Portland Traction Company abruptly (and possibly illegally) ended service on January 25, 1958.
