The Willamette Shore Trolley is a heritage railroad or heritage streetcar that operates along the west bank of the Willamette River between Portland and Lake Oswego in the U.S. state of Oregon. The right-of-way is owned by a group of local-area governments who purchased it in 1988 in order to preserve it for potential future rail transit. Streetcar excursion service began operating on a trial basis in 1987, lasting about three months, and regular operation on a long-term basis began in 1990. The Oregon Electric Railway Historical Society has been the line's operator since 1995.

The Southern Pacific Red Electric Lines, also known simply as the Red Electric, was a network of interurban passenger train services operated by the Southern Pacific Railroad in the Willamette Valley of the U.S. state of Oregon from 1914 to 1929. The service got its name from the bright red color of its cars. Despite its short history, among West Coast interurbans it was unique, and it was considered the finest such system in the Pacific Northwest. It was the only major electric interurban railroad converted from steam to electric passenger use. It was also one of few systems using all-steel equipment, and one of the largest 1500-volt systems in the country.
