July 23-26, 2009 the TrainFestival 2009 rolls into Owosso. The Steam Railroading Institute is hosting the event and says:

Steam and Diesel Locomotives from around the country will be on display for visitors to tour the cabs, take photos, watch demonstrations and much more. Huge model train layouts will be on display including a massive all-Lego model train. Railroad vendors from around the globe will have unique items for purchase that you won’t find any where else. Families will be able to take an all day excursion or shorter one-hour train ride behind various vintage locomotives. For the thrill seeking visitor, you will even be able to pull the throttle and blow the whistle on one of these steam locomotives. Scaled down miniature trains will be hauling passengers around the grounds of the event as well.

One of the trains on hand will be Daylight 4449 (photo courtesy Wikipedia) - the last remaining operable locomotive from the art deco era and the trail that was selected to pull the American Freedom Train for the Bicentennial in '76 (click the picture to see bigger). You can learn all about it at that link and even follow along with its progress towards Owosso via their twitter feed.
