"Beer production has been an important part of Wisconsin's history and economy," Museum Curator Daniel Liedtke said.
"This exhibit focuses on the importance breweries in Milwaukee had on the railroad to both receive the raw materials they needed and then to transport their finished product throughout the state."
The Beer Line ran freight trains that carried grains to the breweries and finished beer to surrounding communities.
The exhibit will run through the rest of the year and ticket costs are included in the daily admission price.
Located in Ashwaubenon, Wisconsin, the National Railroad Museum was founded in 1956 by community volunteers and is one of America's largest and oldest institutions dedicated to the preservation of its railroad history.
An exhibit dedicated to the Milwaukee Beer Line may seem niche, but the line isn't without ardent fans. On Facebook the private group "Milwaukee Road Modelers' has almost 2500 members.
The public group 'Remembering the Milwaukee Road Beer Line' has almost 740 members who regularly post archival footage, anecdotal stories of working on the line and advice for how to build miniature replicas.
