The Portland Traction Company, a now-defunct railroad, operated a rail line from Portland (near the current location of the Oregon Museum of Science and Industry (OMSI) on the Willamette River) to Boring via Gresham. In the 1950s, the Southern Pacific and Union Pacific railroads jointly took over operation of the remaining portion of the line for freight operations. Much of the line has since been purchased by local governments for the creation of a long-distance rail trail named the Springwater Corridor.
