"Strong arm" levers 6 through 11 at the Delray Tower interlocking plant in southwest Detroit.  Delray is a CSX staffed tower which controls former New York Central, Pere Marquette, Union Belt of Detroit and Wabash lines.  The current tower, which is one of the last remaining staffed interlocking towers in the Detroit area, was built in 1945.  At one time, the levers controlled pipes which operated switches and signals.  Now, all signals and switches are electrically operated, but the lever frame prohibits conflicting train moves.  2003 photo.
