110 is a 2-6-6-2 under a full head of hissing steam as it goes over the nearby creek. It has left the station and is beginning the climb up the 4%-6% grade out of Hill City, South Dakota, the infamous Tin Mill Hill. The engine makes lots of noise and smoke as it goes. The 110 is a Baldwin 2-6-6-2T Mallet, built 1928, and the last operating model of its type.
