Located at 16720 Pioneer Road in Middlefield, OH Corner Field Model Railroad Museum and Hobby Shop is DEFINITELY worth a visit. They have constructed a very LARGE O gauge layout and they are in the process of doubling the size of it.
The layout is one of the largest family owned O gauge layouts in Ohio. The layout has over 2,800 feet of track with hundreds of freight cars and a multitude of locomotives. The layout also contains over a thousand buildings and lights along with automobiles, trees and other scenery. The railroad is set in a freelance style ranging from the 40’s to the modern era of railroading.
While there is a lot of the layout captured in the video that along with the description still does not give you the full experience of this layout. You definitely need to visit this layout in person.
