The Midwest Old Threshers Reunion is an annual event that takes place in the small town of Mt. Pleasant, Iowa, United States, and runs for five days, ending on the Labor Day weekend. It was first held in 1950, and has taken place every year except 2020, when it was scrapped caused by the COVID-19 pandemic. When first started, it focused on steam engines and antique agricultural equipment, but has developed into an entertainment event with a wider remit. The tiny town of less than 10,000 inhabitants is invaded by many times that number of visitors, drawn from around the world. Old Threshers Reunion, as an event, attracts visitors from around the world, attracted by both the permanent exhibits on the reunion grounds and by the collections of antique and steam powered equipment brought to the show by other visitors.
Permanent Exhibits
The Heritage Museum is open year round, featuring a variety of exhibits that celebrate the rural heritage of the midwest. The Stationary steam engine exhibit features three large Corliss engines as well as a number of smaller engines. The Midwest Electric Railway operates a trolley line around the reunion campground. A number of well restored Iowa trolleys operate on this line, including Waterloo Car 381, the last trolley to operate in public service in Iowa and Car 9 from the Albia Interurban Line. MERA also operates Car 320, a beautiful wooden interurban from the Chicago Aurora and Elgin line in IL. Additional favorite cars come from as far away as Rio de Janeiro, Brazil and Milan, Italy. The Midwest Central Railroad operates a narrow gauge railway around the reunion exhibit area. This railroad features a 3-truck Shay locomotive from the West Side Lumber Company railway. Other engines include two 2-6-0 Baldwin engines that formerly served logging railroads in the eastern United States and a German 0-4-0 built by Henschel & Son. For routine operations, there are two Plymouth Locomotive Works diesel switch engines and a Vulcan Iron Works gasoline switch engine. In addition to operating during the reunion, the Midwest Central Railroad has public events connected to Independence Day, Halloween and Christmas. The Hazel Grace Pierson Carousel Pavilion houses a beautiful fully restored antique carousel. "The Smile Machine" is powered by a Herschell-Spillman steam engine that dates back over a century. The carousel includes a Military Band Organ, as well as the usual rocking horses.
