Take a walking tour of western Pennsylvania at the world-renowned Miniature Railroad & Village®.

This beloved exhibit's story began in 1920 with a man named Charles Bowdish of Brookville, Pa. Originally a holiday display on the second floor of his house, it moved to the Buhl Planetarium in 1954, and ultimately found its final home at Carnegie Science Center in 1992.

The Miniature Railroad & Village® features hundreds of wonderfully realistic animated scenes that illustrate how people lived, worked, and played in our region during an era spanning the 1880s to the late 1930s.

A replica of the Westinghouse Atom Smasher is the latest addition to this extraordinary display. The Atom Smasher could accelerate particles at 50 million miles-per-hour ushering in the first large-scale research into nuclear energy in the late 1930s and its unique, light-bulb shape housed the largest and most powerful commercial Van de Graaf generator in the world.
