Okay, here is an interesting one for you!  Number 1104 is a 65-ton Porter built in 1942 for the US Army (number 7024).  It was acquired by  San Jacinto Ordnance and later by the Alaska Railroad in 1947.  It was sold to South Dakota Cement Plant in 1954 (number 7425) where it remains today.  A neat bonus to this photo is number 216 hiding in the background.
