The Saxonburg house and workshop of John Roebling, who designed and built wire rope suspension bridges, are re-created in the Carnegie Science Center's Miniature Railroad & Village.

PITTSBURGH — Carnegie Science Center's Miniature Railroad & Village is celebrating its 100th season and has several sites from Butler County represented.

Replicas of the John Roebling House and Workshop in Saxonburg, a billboard featuring a Bantam Jeep, and the Old Stone House on Route 8 have been added through the years.

New this year is a historic replica of the Kaufmann's Department Store and clock. The department store was founded by a family of Jewish-German immigrants in the 1870s as a simple men's clothing shop on the South Side and eventually grew to be the downtown giant many Western Pennsylvanians affectionately remember.

Visitors to the miniature railroad can see a replica of the original downtown store, known as the “Grand Depot,” complete with 15 window displays, a Swarovski crystal chandelier, and delightful details that bring the magic of Kaufmann's to life in miniature.

“The Kaufmann's model brings to the miniature railroad a sense of activity, life, and local pride,” said Patty Everly, curator of the center's Historic Exhibits. “Visually it's very captivating because it is such a big piece. It brings diversity to our display and helps us tell the immigrant story.”

The sprawling layout was first created by Charles Bowdish in 1919 and displayed at his home in Brookville, Pa., to entertain the guests at his brother's wedding. In 1954, the display moved to Buhl Planetarium and Institute of Popular Science in Pittsburgh.Relocated to the Carnegie Science Center in 1992, the miniature railroad includes more than 100 cleverly constructed animations, 250,000 handmade trees, and replicas of historic Western Pennsylvania landmarks.In addition to the three Butler County sites, other miniature representations include the Primanti Bros. restaurant in the Strip District, Forbes Field, the Rachel Carson Homestead in Springdale, and Punxsutawney's Gobbler's Knob.One-hundred years is a long time, and the train display needs significant repairs. In the spring, the science center will launch All Aboard! The Miniature Railroad & Village 100th Anniversary Campaign, a crowdfunding effort to help the center repair wear and tear on the layout, renovate the gallery, digitize the miniature railroad's archives, and enhance the visitor experience.The miniature railroad display is open during the science center's regular operating hours, which are 10 a.m. to 5 p.m. daily except closed Tuesdays, and is included with general admission.The center is at One Allegheny Ave. Visit carnegiesciencecenter.org or call 412-237-3400.

A replica of the Old Stone House in Brady Township, just south of Slippery Rock, can be found in the Carnegie Science Center's Miniature Railroad & Village display.

Carnegie Science Center's Miniature Railroad & Village includes a billboard advertising the Bantam Jeep, which was made by the American Bantam Car Co. in Butler.
