The Oregon Pony was the first steam engine to run on the Oregon Portage Railroad from 1862 to 1863 with freight and passenger service, on the southern bank of the Columbia River, between Bonneville and Cascade Locks. It was once located in front
of Union Station in Portland.
It was on display at Union Station in the 1930s, but was given to Cascade Locks in 1970, restored in 1981, and is now on permanent display in a weatherproofed enclosure at Cascade Locks Marine Park near the Cascade Locks Historical Museum.
Thanks for the update Dave.
