Here is my collection of HO gauge (1/87) detail pieces. Even a small model train layout would require hundreds of these types of details. The more details, the more believable scenes become.
There are close to one hundred finished detail pieces in this storage box. Just a start to all of the details that will be added to one scene at a time. Individual scenes might include structures, both large and small, detail parts, figures, vehicles, and landscape elements such as grass, trees, and shrubs.
