Duplainville History

Duplainville, Wisconsin, an unincorporated community within the City of Pewaukee, is located about 15 miles west of Milwaukee at Milepost 102.2 on the CP main or Milepost 102.6 on the WC. It is between Waukesha and Sussex, Wisconsin. In about 1855, the Milwaukee Road built its track west from Brookfield Junction toward Portage and Minneapolis for a faster route than what had been over the Prairie du Chien Line to the Mississippi river or the Northern Lines thru North Milwaukee, Rugby Jct, Hartford, Horicon and Beaver Dam. In 1885-86, the Wisconsin Central Railroad built south from Rugby Jct to Chicago. Hence their tracks crossed in Duplainville.

A tower was erected in the northwest quadrant of the diamond in 1890. William Alvord was the chief operator for many years.   He lived a short distance from the crossing.  With heavy winter snow, additional help was hired to keep the tracks and switches clear.  Although there were signals and gates at the Duplainville Road highway crossing, there were numerous accidents and some lives were lost.  The tower burned down on January 1, 1929.  A new brick building was then built. It was finally torn down in 1987 after a much needed connection track to the old Soo was built and CTC was installed. The diamond was then controlled from Milwaukee. During 1962, the Wisconsin Central, DSS&A and Soo Line combined to what is now known as the Soo Line.  After the SOO Line purchased the Milwaukee Road in 1985, the Old SOO ( former Wisconsin Central ) crossed the New SOO (former Milwaukee Rd. ) at Duplainville.  

As life goes, things are always in a state of change.  In 2001, the Canadian National RR  purchased the "Old Soo", from the then operating Wisconsin Central Ltd railroad which purchased the "Lake States" subsidiary of the "new" Soo in 1987.  The "new" Soo was folded into the Canadian Pacific Railroad as it is today.

Today, Duplainville is the only place in Wisconsin where the CP crosses the CN.




More Duplainville Area History



Today, there are numerous trains that cross the diamond at Duplainville. The Canadian National Railroad runs about 25 trains per day.  There are also moves by the WSOR between Slinger and Waukesha.  The CP runs about 22 trains per day in addition to Amtrak 7 & 8.

Exit and go north on Hwy F to the 3rd stop and go lights ( just north of a Ready Mix plant). Bear right on Duplainville Road and go north about 3/4 mile to the CP tracks. You may park on the south side of Marjean Lane or just south of the tracks on Duplainville Road,

To get to the CN/WC tracks, continue north on Duplainville Road across the CP double main to Green Road. Then right ( east ) to the tracks.  To get to North Duplainville on the CN/WC, just continue north on Duplainville Rd about 1 1/2 miles to Lisbon Rd ( Hwy K ).

WARNING: Please watch your speed when in the area.  The Waukesha Sheriff Dept. run RADAR and LASER, especially on Hwy F/Redford Blvd. They are also on Duplainville Rd occasionally.
