West Chicago JA Tower: C&NW vs. EJ&E

John Markl posted
JA tower in WeGo....sat about a quarter mile north of JB...protected the crossing of the J and the CNW Freeport line...torn down around 1940, with operations consolidated at JB. View is looking from northwest, to southeast, on the CNW....Downtown WeGo in the left background.
[WeGo is evidently West Chicago.]

I added a red line on this 1939 aerial to show the track we are looking down in the photo. The Freeport route used to have a direct connection to the C&NW mainline. I put a blue square around the tower's location.
