what is it?

The Great Northern O-1 was a class of 145 American 2-8-2 "Mikado"-type steam locomotives built by the Baldwin Locomotive Works between 1911 and 1919 and used by the Great Northern Railway until the late 1950s. The O-1s, along with other O Class Mikados of the Great Northern, were used system-wide to pull freight trains. As of today, only one O-1 has been preserved, No.
