National Railroad Museum
The National Railroad Museum is a railroad museum located in Green Bay, Wisconsin, United States.
Founded in 1956 by community volunteers, the National Railroad Museum is one of the oldest and largest U.S. institutions dedicated to preserving and interpreting the nation's railroad history. Two years later, a joint resolution of Congress recognized the museum as the National Railroad Museum. The museum has been a nonprofit 501 organization since 1958.
Its collection of locomotives and rolling stock spans more than a century. Notable items include an Aerotrain; Union Pacific Big Boy No. 4017, one of the world's largest steam locomotives; and British Railways Class A4 No. 60008 Dwight D Eisenhower and train used by the Supreme Allied Commander and his staff in the United Kingdom and continental Europe during World War II.
The Frederick J. Lenfesty Center, an enclosed and climate-controlled structure, built in 2001, houses several of the unique and rarer locomotives and cars. A museum building houses railroad artifacts, an archive, and photography gallery. A standard gauge track rings the grounds. An wooden observation tower has views of the Fox River and Green Bay.
The museum hosted an annual Day Out with Thomas event until 2019, in which Thomas the Tank Engine pulled young friends past the exhibited rolling stock. In October, it hosts "Terror on the Fox", the Green Bay Preble Optimist Club's haunted attraction that includes "haunted" train rides after dark.
Expansion
A $17 million project expanded the indoor display area and added a plaza along the river. Opened on September 20, 2025, it used $7 million in American Rescue Plan Act funds contributed by the state of Wisconsin.Rolling stock
