At Tunnel City, Chicago & North Western previously had a tunnel paralleling north of the Milwaukee Road tunnel. After its tunnel collapsed in 1973, Chicago & North Western obtained trackage rights via the Milwaukee Road through its tunnel and west to Winona, and abandoned its own line. This arrangement continues in use with the successor railroads.
