Tom,
What about the Western Maryland 162 ton Shay ("Big 6") up in Cass Scenic Railway? How do those cylinders compare with the #91 cylinder volume? Not even sure what class that engine falls into. That shay was abnormally large. There was actually one even larger, but thats another topic. Anyways, thats still pretty impressive to hear about Heisler #91. And yes, you're absolutely right about the superheaters. Forgot that they just pre-heat the water. None of the Shays had them from what I read. The Willamette's had them though. Just out of curiosity Tom, I have noticed that #91 is pretty fast on her feet for a Heisler. I'm guessing its around 25mph?
