It is home to 10 pieces of trolley history that are regularly operated on a 2.5 mile loop surrounding the organization's campgrounds.
The volunteer association runs a tourist railroad which operates electric trolleys around a 2.5 mile loop around the Midwest Old Threshers Reunion campground.
Guest prices and hours of operation vary throughout the year based on the activities of the Midwest Old Threshers Association.
Today, the purpose of the organization remains largely the same including the preservation of non-Iowa operated electric rolling stock.
The Chicago Burlington and Quincy depot from Yarmouth, Iowa, was donated and moved to Old Thresher's fairgrounds; it was originally used as the trolley ticket office and gift shop.
