Lowell Ross is in town currently and has identified the original Casey Jones as a Maxwell engine with brass radiator. He says the Cadillac engine and car body now on the Casey is actually a 1913 model rather than the 1915 date quoted numerous places and was originally used to replace the Stover engine and car body of the SN's Stover railcar #1. Apparently the Stover was top heavy and took a dive into a ditch, wrecking the top part of that vehicle. We do have a picture of the Cadillac engine and car body mounted on top of the Stover frame taken in front of the second version of the Iowa-Tiger tram house on the SN.
