Wyoming, MI: (near Grand Rapids, MI:) Lamar Tower: CSX/PM vs. Aban/PC/LS&MS

(Satellite, not only is LS&MS abandoned, but Wyoming Yard has been extended and covers the crossing)

Here's Lamar Tower as C&O GP7 5717 and its freight passes over the Lake Shore & Michigan Southern (later New York Central) line at the southwest end of the C&O Wyoming yards near Grand Rapids, Michigan, in February of 1965. The tower was located a few hundred feet northwest of Chicago Drive between Greenfield and Byron Center avenues, and that bridge way down there between the tower and train is the Chicago Drive ramp over the tracks to the then-new freeway. You can see the LS&MS tracks running side-to-side right behind the tower.
I've included a 1975 city map in the replies that shows where the tower was as well as where the LS&MS line continued into town across what's now the Kent Trails bridge over the river. The last train on the line and last to cross the bridge was in 1976.
C&O electrician Dick Blakely captured the 5717 going by as he and crew were working on nearby signals.

Here's the map of the area showing where the tower and tracks were.

It appears that this cartographer included a rectangle for this tower. That is not typical.
