1st & 3rd Saturdays, 10-2 (Operating session)
Every Tuesday, 7-9 (Work session)
Although it's only open a few times a month, the Luce Line Railroad Club has a nice display of model trains, including a small track that kids can control. It's free, so if your kids like model trains, try to stop in when they're open.
They also sponsor a train show at the fairgrounds in the fall, with even more train displays.
