(Above and below)  Penford Tower was the crossing of the Pennsylvania Railroad and the Detroit, Toledo & Ironton in Taylor, Michigan.  This was one of the last new interlocking towers built in Michigan as the neither the PRR or the DT&I was built at this location until the early 1920's.  The DT&I was owned at the time by Henry Ford, hence the name PenFORD.  The photo below shows the DT&I electrical cement catanary posts which held overhead power supply wires for brief electric operations in the late 1920's.  The tower was photographed by Charlie Whipp in the early 1980's and torn down in 1986.
