This is a question for the guys operating steam engines at tractor shows. I'm assuming you have to have some kind of regular inspection by a government agency to keep them certified to run? If so is it state regulations or federal regulations that you have to be certified to. Reason I'm asking is we have a guy near Buffalo that owns and operates a small steam locomotive and he was scheduled to operate it at our rail road museum in August but he has run into a problem renewing his certification. The federal office in Buffalo that used to have a person closed and he can't find anyone in the federal government that knows anything about it. I'm wondering how getting it done for a tractor is different than getting it done for a locomotive. Are steam tractors more state regulated so no connection to the feds?
