The 7,500-square-foot Model Railroad Garden features trains running on 1,600 feet of track. The garden-scale trains are 1/29th the size of life-size trains. Train and garden enthusiasts, young and old, return year after year for the delightful sights and sounds of the miniature trains traversing high and low through tunnels, across bridges, and around buildings. All are intricately handcrafted with natural materials, including twigs, bark, leaves, acorns, and pebbles. More than 5,000 tiny trees, shrubs, groundcovers, and flowering plants of close to 300 varieties re-create the topographical landscape of America. Vignettes of tiny people and animals give the exhibit a storybook feel, while sound effects and a working geyser capture visitors’ imaginations. The trains travel more than 22,000 miles each season.
