Location: Alexis Tower - Toledo, Ohio
Photo info/credit: Top, Alexis Tower on the north side of Toledo, Ohio. This tower protected the crossing of both NYC main lines to Detroit as well as the Ann Arbor Railroad and the C&O. In its heyday, the tower also saw trains of the Pennsylvania Railroad. 1983. 2nd photo, the interlocking plant in Alexis was a combination of "strongarm" type, as well as two additional electric interlocking machines (green units). These may have controlled nearby interlockings such as "K", just south of Alexis. 1989.
