Steeplecab 51 is a 1921 product of Baldwin Locomotive Works; before coming to the Iowa Terminal operation it was owned by the Oklahoma Northeastern, the Cedar Rapids & Iowa City, and the Kansas City & Kaw Valley. Steeplecab 54 was built by Baldwin in 1923 and served on the Southern Iowa Railway before coming to Mason City. Both locomotives still operate for Iowa Terminal successor Iowa Traction Railway. I took this transparency in July 1973.
