Oregon Railroad and Navigation Co. 197 is a 4-6-2 Pacific type steam locomotive built by the Baldwin Locomotive Works in 1905 for the Oregon Railroad and Navigation Company (OR&N). It has been owned by the City of Portland since 1958, and since mid-2012 it resides at the Oregon Rail Heritage Center, where it can be viewed by the public.

OR&N 197 was built in 1905 for pulling passenger trains on E.H. Harriman's Oregon Railroad and Navigation Company, a subsidiary to the Union Pacific Railroad in Oregon. It arrived from the builders just in time to celebrate the 1905 Lewis and Clark Centennial Exposition. It continued to serve for Portland, Oregon, when in 1923, it was given heavy modifications, a new vanderbilt-type tender, and renumbered Union Pacific 3203; at that time it was owned by Union Pacific. The Union Pacific used the locomotive until its retirement sometime in the 1950s, when UP donated the locomotive to the City of Portland, Oregon. It was placed on display near Oaks Amusement Park, where it was soon joined by the larger and more powerful 4-8-4 type locomotives Southern Pacific 4449 and Spokane, Portland and Seattle 700.

In 1975, the SP 4449 was pulled out of the park to be restored to pull the American Freedom Train which would travel across the country during the United States Bicentennial. In 1990, SP&S 700 left the park to begin a restoration of its own, leaving the 197 the last engine in the park. Due to a parking lot expansion, the 197 was moved a short distance from its original 1950s resting place at Oaks Park. Otherwise, it sat almost forgotten until late 1995, when a small group of individuals banded together to consider returning the locomotive to operation.
