So what little kid, or little kid-at-heart, doesn't like trains? And here you get to see them, climb on them and explore. Honestly, I've only been in the building for the model train show put on every year. My boys just love climbing around the many locomotives and cars that are around the building. Best of all, the outside area is free! If you geocache or letterbox, than this place is a must. I do know the John Browning Museum is inside, but I've never been.
