There are seven interactive points around the layout provided for visitors to operate various functions including a Lumberjack chopping down a tree, blasting for a future mountain tunnel, and an operating drawbridge over the Chicago River. Guests can also send a Metra train on its way after a stop at a suburban station. Up to 34 trains can run simultaneously on 17 tracks including a three-track main line. The display has a number of whimsical scenes including a CowParade, "Star Trek"'s Captain Kirk at the Space Needle, garden gnomes tending part of a forest, a man on a one-way canoe trip approaching a waterfall, and campers encountering skunks and bears. Street and building lights turn on when the exhibition hall's lights are dimmed during periodic demonstrations of the Boeing 727 suspended overhead.
