This 78-year-old veteran works a terminal in Hudson, Colorado. The Alco S1 was built in 1946 for the Detroit & Mackinac Railroad and later operated with the Lake State Railway Company.
The BNSF utilize a couple former Sante Fe Caboose as shoving platforms in the yard in Golden, Colorado. Although tagged by graffiti, it's still good to see a caboose on the active roster.
