(Above)  Postcard view of the Union Station in Dundee, Michigan.  This is the crossing of the Ann Arbor Railroad and the Lake Shore & Michigan Southern (former Detroit, Toledo & Milwaukee Railroad).  The pipe(s) running next to the rails (horizontal rails) connect to the signals at the interlocker - probably from a tower which is out of sight to the right.  Note the three-wheeled velocipede.  (Below) Another photo of the depot.
