I read the article in the Streamliner last night. Up to that point, I didn't understand how they were worked. It was interesting to me that the last two, built by Lima, used a 3 cylinder engine similar to a Shay to power the rotary wheel. I have a Video Rails Hank Griffiths collection video that shows a UP steam-powered rotary in action that I haven't watched in a few years. Unfortunately, the video is on VHS and my VCR stopped working a while back.
