ASHWAUBENON, Wis. — The National Railroad Museum has opened its new Fox River Expansion, a 21,000 square foot, climate-controlled exhibit hall, which faces the waterway running along the museum campus. The $17 million project is the first of four museum expansion phases and has been nearly 10 years in the making. Additionally, facing the Fox River and the museum’s tracks is a 5,000 square foot covered patio. The glass wall gives the exhibit hall an open and inviting feel, and provides a wealth of natural light.
