Yeh I know, but if you review together the several views posted, you will see that there is one there just out of view in your photo. After looking at the view, I notice that there is a large flywheel on one side. It looks a bit like a small "jaw crusher" without all of the other usual equipment that surrounds one. SVRy in 1939 built up a rock crusher unit constructed in their shop of used parts from various sources powered by a Caterpillar 60 gas engine. They used it to crush ballast at a quarry at about mile post 17 and built a spur there. I think this would be under the lake today. They also used the crusher at a quarry over near Bates. That may not be what this is a part of in the photo, but a guess based on what little of it is shown.
