Chicago Ridge tower shortly after it closed in 1994. Tuch says: "NS manned the tower before it was closed and took care of maintenance
on the plant. IHB wanted the place closed badly and cut an unusual deal to eliminate it. In order to seal the deal, IHB assumed all
maintenance responsibility for the plant even though it was technically CSX trackage. CSX did the track work on the CSX/IHB rail and
NS was responsible for the track on their line, but IHB took all switch and signal maintenance. It is the only portion of the CSX-owned
section of the IHB that has such an arrangement. CSX handles all the rest between BI and Superior."

Calumet Park tower, which burned down a few years after this photo was taken. The interlocking was then
controlled from Hohman Avenue tower until it was shut down

Osborn tower, at the crossing of the Kankakee Line and NS's ex-NKP main. It was demolished in the 1980s.
