Great Train Story Layout at the Museum of Science and Industry, Illinois

This $1 million-plus, 3,500 square foot HO model railroad layout, called the Great Train Story, is located in the transportation wing of the Museum of Science and Industry, and is loosely based on the 2,200 miles between Chicago and Seattle. The layout includes interactive buttons that allow visitors to animate scenes, as well as dramatic lighting that switches to “nighttime mode” every half hour.
