The Portland and Willamette Valley Railway was incorporated on 19 January 1885 to continue construction of a {{RailGauge|3ft|lk=on}} narrow-gauge railroad line between Portland and Dundee, Oregon, United States, which had been started a few years earlier by the Oregonian Railway.[https://books.google.com/books?id=2gC82vs_OHsC&dq=Portland+Willamette+Valley+yamhill+gauge+131&pg=PA131 Encyclopedia of Western Railroad History: Oregon, Washington, p. 131][https://books.google.com/books?id=7POj8GvF4sIC&q=Portland+Yamhill&pg=PA481 American Narrow Gauge Railroads, p. 480] The line was opened on 31 December 1886 and the first timetables were published the following day; however, the line did not reach Portland until 23 July 1888, due to disputes over the right-of-way. The railroad company ran this line until it fell into receivership on 2 February 1892.

On 5 August 1892, the line was leased to a Southern Pacific Railroad subsidiary, the Portland and Yamhill Railroad, which ran the {{RailGauge|3ft|lk=on}} narrow-gauge line for another year. The railroad was later taken over entirely by the Oregon and California Railroad, another Southern Pacific Railroad subsidiary, on 1 August 1893 and was converted to {{RailGauge|4ft8.5in|allk=on}} that same year.[http://oerhs.org/wst/ Oregon Electric Railway Historical Society's website about the trolley]

The Portland and Willamette Valley Railway's main line became the Southern Pacific's Newberg branch. The Willamette Shore Trolley runs on a part of that Dundee–Portland line, between Lake Oswego and Portland. The Portland and Western Railroad operates freight service south of Lake Oswego.{{cite magazine | last=Dorn | first=Dick | title=Tracks of the Pioneers | magazine=Trains | date=September 2000 | volume=60 | issue=9 | page=37}}
