Nichols Tower, at the crossing of the New York Central main line with the Grand Trunk Western main line.  This crossing was eliminated in the 1980's when the NYC was routed over the Grand Trunk through Battle Creek eliminating downtown congestion.  Photograph by Charlie Whipp on August 16, 1975.  Below, a broader view of the Nochols & Shepard Company, with the interlocking tower in the foreground.  [Mark Worrall Collection]
