Old photo of this 2-8-0, which was later sold to the American Crystal Sugar Co. at Chaska, Minnesota. It worked there into the late-1950s, but despite a heavy rail enthusiast presence in the Twin Cities, no one knows what happened to it.

If you scroll down on this page on the steamlocomotive.com website, there are photos of the 452 at the sugar factory, plus conjecture that it was scrapped about 1966 or '67. There are also photos of the 457 and 471, which do still exist.

Not all links work, but there is a sketch of a proposed shelter. After some vandalism, they have installed a security camera at the site.
