This section is kind of complicated. Back in the 1980s, two railroads used all of these crossings. One railroad was the Chicago, Milwaukee, St. Paul & Pacific railroad, and the other was the Chicago & Northwestern railroad. Due to these 2 railroads sharing names, most crossings will have two DOT numbers.
The tracks initially split before Clifford St., and the old CN&W line is defunct. County Highway J never had any crossings by CN&W.
When the UP bought all the rights from Chicago & Northwestern, they really let most of the tracks and crossing really go downhill rather quickly. A lot of tracks are in bad shape that they can NEVER be repaired, all because UP found those lines to not make enough money. Very shameful. I just hope that some stuff can be saved in the long run...
Chicago, Milwaukee, St. Paul & Pacific Railroad went bankrupt in 1985, and sold most of their trackage to SOO in 1986.
SOO then sold part of its railroad lines in 1987, which was bought by Wisconsin Central, then became Canadian National on October 9, 2001 due to a merger, then became Wisconsin & Southern Railroad in 2004 after Canadian National abused the line, then wanted to abandon it most of it.
The state of Wisconsin HAS just purchased the former C&NW/UP line (the overgrown, out-of-service appearing track in some of the Reed Street and Main Street @ Milwaukee Street photos) for future rehabilitation and operation by WSOR.
