I have always believed that the southbound automatic 13 signal was an "advanced home" or "repeater" signal for CP10.
If that is true, then whatever aspect CP10 is displaying should be the same on auto 13, right?
This morning I am watching the webcam at New Bridge road in Bergenfield and can clearly see that CP10 is an approach-medium.
A southbound train reported auto 13 to be clear.
When he reported for CP10 he did indeed report the approach medium I was seeing on the webcam.
The train was lined for track 2, so he was allowed to proceed at a higher speed over the switch than if it had been lined for track 1 or the middle siding.
So, I'm thinking that auto 13 is not a simple repeater or advanced home signal, but reads the position of the switch at CP10 as well.
Edit: That webcam at New Bridge road in Bergenfield (https://www.youtube.com/watch?v=WFUjU2zu9JU

Edit #2: Watching same webcam later today. CP10 was Medium Clear, sobo train reported Approach Medium at auto 13. So it's not a true "repeater" signal, is it.
I believe that someone once told me that auto 13 (southbound only) has some advanced aspects, but not the full set that a CP can display.
