His model train tree is now six levels instead of the five it was a year ago.
Miller, who lives in the Rising Sun area, has been a model train enthusiast for a half century.
About 25 years ago, he began creating a train tree, which has grown and features different types of trains - Garden, HO, Lionel, Marx, and N Scale. Each train set has its own layout and some of the models and accessories date back to the 1920s. All the trains operate independently or can run simultaneously. He has worked to fine tune the operation and spent hours working on the mechanics.
