When are the train rides for the public in Maury county city park? This was on Tennessee Crossroads

I saw two guys dropping off wood for the steam engines two weekends ago. I don't know there schedule.

These trains are called The Tennessee Steamers.They come to Maury County Park and let everyone ride these little trains.They come ever year but I'm not sure how it will work out this year.Also it's located In Columbia Tn not Lewisburg.Ty would you mind telling me if you remember when you saw this on Tennessee Crossroads ty very much
