In 1855, theChicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road) built a railroad line fromBrookfield toWatertown, which eventually went toPortage. In 1885, theWisconsin Central Railroad built a railroad line fromRugby Junction toChicago. This eventually led to their tracks crossing in Duplainville. In 1890, a tower was built in the northwest quadrant of the diamond. Because of heavy winter snow, help was hired to keep the tracks and switches clear. Although there were signals and gates at the Duplainville Rd crossing, there were numerous accidents and some fatalities. The tower burned down on January 1, 1929. A new brick building was then built, which was torn down in 1987 after an interchange track was installed in the northeastern quadrant of the diamond connecting the two lines.
The line built by the Milwaukee Road eventually fell under the ownership and control of theSoo Line Railroad in 1986. Canadian Pacific assumed full ownership and control of the line in 1990 after purchasing the Soo Line (CP merged with Kansas City Southern in April 2023 to form CPKC). The line built by Wisconsin Central went through the ownership of various railroads before being handed to Canadian National in 2001.[3]
The interchange switch on the CP side was removed on or around August 1, 2019 due to a dispute over where in Chicago the railroads should interchange and a lack of activity.[citation needed]
The diamond junction in the center of Duplainville attracts many rail enthusiasts and railroad photographers due to around 20–25 trains that run through each line per day.[2] The east–west mainline belongs to CPKC's double-trackedWatertown subdivision, which operates under theSoo Line Railroadsubsidiary although Amtrak'sEmpire Builder andBorealis services also use this line. Duplainville is at milepost 102.2. The north–south mainline belongs to theCanadian National Railway's single-trackedWaukesha Subdivision, which operates under theWisconsin Central Ltd. subsidiary. Duplainville is at milepost 102.6.[4] TheWisconsin and Southern Railroad also hastrackage rights over this line.
