The Wyeville Subdivision or Wyeville Sub is an {{convert|82.8|mi|adj=on}} railway line owned and operated by the Union Pacific Railroad. It meets the Altoona Subdivision to the west in Altoona, Wisconsin and runs to Wyeville, Wisconsin to the east where it connects with the Adams Subdivision.{{Cite web|url=https://www.loc.gov/resource/g4121p.ct001917|title=Official railroad map of Wisconsin|date=1900|website=Library of Congress}}{{Cite web|url=https://wisconsindot.gov/Documents/travel/rail/railmap.pdf|title=Wisconsin Railroads and Harbors Map|date=2020|website=Wisconsin DOT}} Construction began in 1868 by the West Wisconsin Railway and was completed in 1872. The line then became part of the Chicago, St. Paul, Minneapolis and Omaha Railway in 1878; the Chicago and North Western Railway acquired control of this road in 1882. The CNW then became part of UP in 1995.

The last passenger train to run on the line was the CNW's Twin Cities 400, which operated from 1935 to its discontinuation in 1963.{{cite web|title=Wyeville Subdivision|url=https://www.chicagorailfan.com/rfttucwy.html|website=Chicago Transit & Railfan}} In July 2019, Union Pacific 4014, a 4-8-8-4 Big Boy type steam locomotive, ran on the line as part of the "Great Race Across the Midwest" excursion.{{cite web|title=The Great Race Across the Midwest: Big Boy No. 4014 Locomotive To Cross Rock River In Wisconsin and Illinois|url=https://rockrivertrail.com/the-great-race-across-the-midwest-big-boy-no-4014-locomotive-to-cross-rock-river|website=Rock River Trail|date=8 July 2019}}
