ID=11376017(WBIR-Oak Ridge ) Model trains aren't just for children. A lot of grown-ups enjoy more sophisticated versions of what you may have played with when you were younger.

The Children's Museum of Oak Ridge features trains the adults in the Knoxville Area Model Railroaders helped build.

One of the most popular exhibits at the museum is the World of Trains.

It was inspired by models donated by longtime Oak Ridge model railroader Milton Lloyd and built by members of the Knoxville Area Model Railroaders. The World of Trains wing contains a hands-on play room with a mock-up of a diesel engine and a large HO scale layout called Lloydstown.

The exhibits are open to museum visitors every day.

In addition, the wing contains the club rooms of KAMR, a full-size Norfolk Southern caboose, and a garden railroad which are open to museum visitors the third Sunday of each month.

Call the museum for hours.
