The Oregon Rail Heritage Center in Portland, OR, opened to the public on 22nd September 2012. Establishment of the center was led by the Oregon Rail Heritage Foundation, a non-profit organisation set up in 2002 "to secure a permanent home for the City of Portland’s steam locomotives, preserve the Brooklyn Roundhouse, and establish a Rail and Industrial Heritage Museum".
The three locomotives were donated to the City of Portland in 1958 and were placed on static display at Oaks Amusement Park until the mid-1970s. A new development at the park then meant they had to be moved and they were consequently relocated to the Union Pacific's (formerly Southern Pacific's) Brooklyn Roundhouse.
UP’s plans to demolish the roundhouse in 2012 to create additional yard space instigated construction of new accommodation. After considering other potential sites for an enginehouse, the ORHF reached agreement in 2009 on a site near the Oregon Museum of Science and Industry. Demolition of Brooklyn Roundhouse was carried out in September 2012 at which time, the three engines were moved to the new heritage center.
