Great photos! Two I had not seen. I believe that the Marion steam shovel went to OLC at Bates when it was retired from SVRy. OLC used it to unload log cars. Someone, maybe SVCartoad, told me that the engineer of a log train would run the former shovel while the fireman moved the train along as needed to unload log cars. I don't believe the pile driver mechanicals were related to the Marion Shovel. The AFE's show SVRy purchasing a couple different gas driven crane/shovel's after they retired the steam shovel.
