Winton:
Thanks for pointing this out. I was aware of these signals because they show on the alignment chart, but I never saw them and because the blade is drawn downward, I just assumed, erroneously, that they were lower quadrant.

Subject: Re: [CBQ] CB&Q Semaphores
Where I worked on the former CB&Q dark territory in Wyoming in mid 1970s some of the sidings had spring switches on one end and yard leads had a spring switch. In all of these cases there was a Distant signal that was an upper quadrant
semaphore that could show only vertical Green or 45 degree Yellow. At the siding's spring switch there was an upper quadrant semaphore that could show only vertical Green or horizontal Red depending upon whether the spring switch points were properly seated
or not for facing point mainline movement. These spring switches had no point locks so there was no signal for trail-thru movement off the siding.
