This was the original starting point of the Winona and St. Peter Railroad. It became the starting point for the Chicago and North Western Railway Minnesota Division, and then their Dakota Division.Chicago and North Western Railway Track diagram, 1959 The C&NW sold off most of the Dakota division to the Dakota, Minnesota and Eastern Railroad. It kept the downtown Winona trackage to switch the barge terminal and businesses. The track from Tunnel City, Wisconsin to the Winona Rail Bridge eventually was abandoned when the tunnel collapsed in March 1973. The Chicago and North Western rerouted to the older Milwaukee tunnel. The CNW route, to Onalaska and Winona, is now abandoned west of the 1910 tunnel. The Winona Rail bridge was no longer used by 1977 and the swing span was removed in 1980.Farrey, Karriann - Winona: Sites then and now Winona Daily News, September 29, 2018 The Union Pacific Railroad, which purchased the C&NW, has trackage rights from Tunnel City through La Crosse on the Canadian Pacific track.Trains Hotspots: LA CROSSE, WISCONSIN .
