Thanks -- that was quite helpful. Of course that led to further questions --
It seems that LRoutes and Double Crossovers only understand Signal Heads and not Masts. So how do I associate a Signal Mast with a crossover (I only get the option to place Signal Heads)? I did manage to place a Signal Mast at the boundary of the next track segment and it successfully discovered the correct destinations through that crossover. Perhaps my problem is that I (luckily?) created my double crossover with track segments out of each of the four corners.
I finally find the "LRoute Initializer" under the "Add LRoute", as a radio button. It sure would be nice if that were documented somewhere. (Based on your mention of it I started digging and finally found it -- the only mention seems to be where Bob Jacobsen calls it out in the release notes for 2.12). I'll use that to set up some of my sensors, though it looks like I can't actually set Masts.
