History

In 1905, the Oregon Railroad and Navigation Company (OR&N) purchased four locomotives from the Baldwin Locomotive Works as there was a large amount of passenger traffic caused by the Portland Fair of 1905. [1]

OR&N 197 was retired in 1958 and was donated to the City of Portland. Where it was placed on display near Oaks Amusement Park on land the city purchased for a future transportation museum, then named "Oaks Pioneer Park", where it was soon joined by two examples of the larger and more powerful 4-8-4 "Northern" type locomotives, Southern Pacific 4449 and Spokane, Portland and Seattle 700 as well as some other historic railroad and interurban equipment. [2]

It had sat almost forgotten by the public until late 1995, when a small group of individuals banded together to consider restoring the locomotive back to operational condition.

By 2008, the restoration was about half complete and was expected to be completed as volunteers and funds are available. It was being carried out by the non-profit all-volunteer group called the Friends of the OR&N 197.

As of 2024, OR&N 197 is still in the Oregon Rail Heritage Center (ORHC), being restored to operating condition by volunteers.

The Shay locomotive is a geared steam locomotive that originated and was primarily used in North America. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive. Although the design of Ephraim Shay's early locomotives differed from later ones, there is a clear line of development that joins all Shays. Shay locomotives were especially suited to logging, mining and industrial operations and could operate successfully on steep or poor quality track.

<i>Oregon Pony</i>

The Oregon Pony was the first steam locomotive to be built on the Pacific Coast and the first to be used in the Oregon Territory. The locomotive, a 5 ft gauge gear-driven locomotive with 9 in × 18 in cylinders and 34 in (860 mm) drivers, was used in the early 1860s to portage steamboat passengers and goods past the Cascades Rapids, a dangerous stretch of the Columbia River now drowned by the Bonneville Dam. Steamboats provided transportation on the Columbia between Portland, Oregon and mining areas in Idaho and the Columbia Plateau. Portage was also necessary at other Columbia River navigation obstructions, including Celilo Falls.

<span class="mw-page-title-main">Union Pacific 618</span> Preserved American 2-8-0 locomotive

Union Pacific 618 is a class "C-2" 2-8-0 "Consolidation" type steam locomotive previously owned by the Union Pacific Railroad. The engine is now located in Heber City, Utah and owned by the Heber Valley Railroad. Built in July 1907 by the Baldwin Locomotive Works (BLW) of Eddystone, Pennsylvania, No. 618 is one of 2 surviving Oregon Short Line C-2 locomotives. The locomotive operated in revenue service until 1958. It was then donated to the State of Utah, where it sat on display for many years. In the mid 1960s, a full restoration effort began on the locomotive with the promise of heading up Utah's first tourist railroad in Heber City after the state donated the engine to the National Railway Historical Society. Today, it is one of UP's oldest locomotives and the first steam locomotive to be removed from a Public Park, and put back into operational condition in excursion service. The engine currently is out of service in Heber City, Utah undergoing restoration back to operating condition.
