Hi Tom,
I believe the eastbound (southbound) hi rail is on the Q main and the Milwaukee interchange track switch that is part of the interlocking. The signal is for the interchange track.
Use to spend much time at that tower in early 1970's.

Very interesting signal. Appears to be standard Q searchlight signal with the spiked filial and lower signal head for diverging. You can see the car is sitting at a switch. My first guess was that the switch is the connection from the Q to the MILW. But I also
found the location of the signal interesting. It is up around the frog of the switch. The hyrail appears to be actually beyond the switch points. I would have thought the signal would be located before the switch points so there is no chance of a crew fouling
the switch points. I have not had time to go back and search the track diagram for this interlocking, but my guess is that the signal protecting another switch just to left of the the photo, as well as the diamond. Is this the case?
Interesting view for the low location of the lower diverging signal head. Of course, most interesting is the second short mast. What is it for? Is that a small lunar signal mounted on it or something else?
