All Aboard

Experience the wonders of the rails when you explore All Aboard, Discovery World’s new model railroading exhibit!

Whether you’re a full-blown train enthusiast or enamored by the marvels of miniature worlds, your family won’t want to miss this replica of mid-20th century Milwaukee equipped with a dynamic landscape including local buildings such as the historic Everett Street Depot, Pabst Brewery, Usinger’s Factory, and much more.

Explore the science behind the trains and learn why trains and railways have been a ‘model’ of innovation for hundreds of years, leading to advances in industry, agriculture, and transportation. Powered by steam, diesel fuel, or electricity, trains represent one of the most important ways that people and goods travel.

Today, trains and railways embody technological advancements from around the globe. From smart sensors and automated inspection equipment to computer programs that maximize fuel use, trains continue to carry us into the future.

The model railroad layout featured in All Aboard was made possible through the generosity of Richard (Dick) Grigg and his family. Dick’s family has donated this layout as a memorial to Dick, for the entire community to share in his passion and enthusiasm.

Exhibit supported in partnership by Walthers.

Wind Leaves

Created in 2006 by nature artist, Ned Kahn, Wind Leaves is a series of soaring aluminum columns that rotate with the wind. Located right outside Discovery World, the Leaves are covered with thousands of stainless steel disks that swirl and ripple with the wind, creating a kaleidoscope of reflections from the lake, the sky, and the city.

The Wind Leaves are surrounded by musical benches that can be played like xylophones and a musical sculpture that you can play by dropping pebbles into it.

Make waves on The Challenge!

The Challenge is a replica of a Great Lakes Schooner that sailed 1852-1889.

The original vessel was built by a 25 year-old shipwright named William Wallace Bates, who had only an 8th grade education and influenced shipbuilding by including the use of a retractable centerboard. The Challenge was the semi-truck of the Great Lakes.

The replica was built in the fall of 2005 by master builder Rob Stevens. Experience the living and working conditions aboard a 19th Century sailing vessel, and learn more about the physics, science, and technology of sailing.
