Tower A-20: UP/C&NW vs. UP/C&NW

Where the C&M and the new line split, and further down the old CNW route near northbrook illinois... Taken with permission from a good metra employee.Glen Warmann Tower A20Stuart B. Slaymaker Site of Tower A-20, to us oldsters. Armstrong tower. Some of the longer levers required the tower man to leap on them, and ride them down, to lock. True story. Circa 1967.
I assume the C&M was the Chicago & Milwaukee. The "new line" would be the line that goes southwest across the northern suburbs, then south along the west side of O'Hare, then back east to Proviso Yard to take freight trains more directly to UP/C&NW's freight yard.

In the background, you can see the lattice truss bridge that takes the new line over the old line.

I put a red rectangle around the building that I believe was the tower based mainly on the shadow of a chimney and the proximity to the turnout and signals.

Carl Venzke caught a Milwaukee commuter in March 1959 with a signal in the foreground and the tower in the background.

Metra posted a video of "Metra and Union Pacific crews replacing the final switch at Tower A2 in August 2016." What I find amazing is that UP used two rail-mounted cranes. Since they used their own cranes, I assume they used their own crews. When BNSF replaced crossover switches in Downers Grove, they hired multiple contractors. Cranemasters provided the crane service with three crawler cranes. (Their pre-assembled crossover was a lot longer than this one.)
