BRC 55th Street Junction Tower: BRC vs. BRC+IHB

Old: (Satellite, according to the aerial photo below, the tower was in the southwest quadrant.)

The connecting track behind the tower didn't make sense for the southwest quadrant so I dug deeper and discovered a newer tower was in the northwest quadrant.

New: (Satellite)

This is the new tower, and it was in the northwest quadrant of the crossing: https://maps.app.goo.gl/rSMN7YdiN5HWt4cc6. Diagram is from https://northamericaninterlockings.com/illinois_9.html.
