Here's a view most people will never get to see of the valve motion on a Heisler Logging Locomotive while going down the tracks.
This is the Stephenson County Antique Engine Club's, Silver Creek & Stephenson Railroad or SC&S RR, which runs several times during the year including runs on Memorial Day, Fathers Day, 4th of July, Labor Day, and during the Threshing Show aka the Freeport Show which is held up the road at the Stephenson County Fairgrounds.
The railroad is accross the road from the Silver Creek Museum which also has a huge 130 Ton Cooper Corliss stationary steam engine with a 26 foot diameter flywheel, (actually 26' 4" diameter) with over 85 Tons of rolling mass.
