Super 8 sound movies from around 1980 taken inside the interlocking towers at Milan, Michigan (N&W and Ann Arbor) and at the Conrail-Grand Trunk crossing at South Bend, Indiana. Milan was an Armstrong plant whose rods appeared to have needed some oiling.

The remainder of the video is footage that was on the same film reel taken on Conrail's Chicago Line in Indiana that isn't long enough to warrant its own video.
