I worked as a volunteer on a for profit steam restoration about 11 years ago. I knew my efforts were going to help someone else make some money if everything went right. How this individual acquired his steam locomotive(s) made a lot of people pissed off, but he got what he needed to try make a project work. It didn't, but I had a lot of fun working with the crew, bringing a locomotive back to life and see it run for a few months. What I did learn, there's an amazing amount of ego involved about what various people do in the steam world. glad that my involvement was short and focused and then I exited when the locomotive existed. Never-the-less, it was fun, I learned a lot and got to use really big wrenches.
