           Summit sat on the top of a long grade that 
      started at the Scioto River in Columbus.  It was here that trains 
      could be switch from one track to another and where, in the steam 
      days, helper locomotives would be cut off and sent back to Columbus.  The 
      tower had a manual lever plant.  It was a B&O tower staffed with a B&O 
      operator.
