Thanks Tony. I will put some time on the steam engine as all of you suggested. I was able to established the manufactured date. It was built in 2009. So it appears to be of the latest design. All in all I am happy with the product. I was under the impression that all flywheeled engines run smooth like the Kato's. I do not own any Kato's steam engines yet. Are they of the same quality as the diesels?
