Oregon Railroad and Navigation 197

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). Since the OR&N was controlled by E.H. Harriman at the time, this locomotive bears a strong resemblance to Southern Pacific locomotives of the same era, since the Southern Pacific was another E.H. Harriman controlled railroad. 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.
