Cool stuff. There is a guy near me that collects the old industrial engines  (much smaller, nothing approaching the scale of those), they get them out for the Founder's Day parade and fire them up every year. Neat to watch them run.

Thanks, will have to check it out next time I'm in that part of PA. There are some neat oil pumping engines, powers and jacks on display at one of the restored sites in the Allegheny National Forest. I can't remember exactly where it is, but I'm sure it is located in the Bradford Ranger District.
