Until 1891, Green Bay Route trains entered Winona via trackage rights through this yard.

What's a Chicago & North Western photo doing on a Green Bay Route web site?

In 1873 the Green Bay Route reached the banks of the Mississippi River and used a trackage rights agreement with the La Crosse, Trempealeau, & Prescott Railroad (controlled by the  C&NW) to use their bridge over the mighty river. 

Green Bay, Winona, & St. Paul trains would enter Winona over the curving trestle in the foreground and then back under it to their own station in the city.

By 1891, the agreement with the C&NW had become oppressive, limiting the GBW&StP to one mixed train a day.  The agreement was terminated in 1891 when the Green Bay Route obtained direct access to Winona through part ownership of the Winona Bridge Railway Company.
