Okay, so it's not high culture as we know it, but this museum is cool and pleasing, and worth 30 to 60 minutes of your time, especially if you have kids in tow. Six permanent, scale-model railroads depict Southern California's transportation history and terrain with an astounding attention to miniature details--the exhibits occupy a 24,000-square-foot space. Children will enjoy the hands-on Lionel trains, and train buffs of all ages will appreciate the interactive multimedia displays. Allow a half-hour to an hour for your visit.
