Green Bay & Western flatcar #141 was dedicated to intraline shipment on the railroad's Sturgeon Bay division between two Van Camp milk plants.   The car is shown on track 2 at the Van Camp (later Evangeline Milk) plant in Sawyer.

Before the mid-1940s,  the Van Camp plant in Casco was simply a milk receiving station.  The milk was gathered from local farmers, and then loaded onto those uncovered milk flat cars for the trip up to the Van Camp milk condensary in Sawyer -- this was in the days before Van Camp had a large fleet of trucks for making milk pick-ups throughout Door and Kewaunee Counties. Rail was the fastest way to ship that much milk between Casco and Sturgeon Bay, especially in winter when snowy weather made the roads impassable.

After the trucks were introduced (and Evangeline took over both plants in 1937), the Casco plant went from milk receiving to cheese production, but really didn't start producing in great quantities until a major plant expansion in 1949. By the time the 1940s came around there was a truck line, operating between Casco and Sawyer for Evangeline/Casco Cheese, transporting milk between the two plants. It seems that Casco used more milk than their farmers could provide and the raw material was trucked down from the Sawyer plant.
