Frog Juicers compatible with RailPro?
Tom:
Bruce,
Have you tried connecting RT1 & RT2 from same AR-1 to two different frogs which would never be crossed simultaneously? Or for that matter splitting RT1 & RT2 with each output going to two or more frogs all of which would never be crossed simultaneously. If this is possible and all runs are shorter than 10 feet from AR-1 the cost per frog would be cut drastically. In any event, what would happen if two connected frogs were touch simultaneously: maybe the PWR-56 would just cut off power for 2 seconds and then one would move on?
Also there would be less wiring more like the Frog Juicer, rather than having 5 wires connected for each SmartFrog V5 which also looks like less expensive decent option. Though retrofitting a Caboose 220S proved more messy for me than the SmartFrog V5 would be (I wired a SmartFrog V4, but it did not work).

Tom,
That's a great question. If the train gods are in my favor today I should be able to give you your answer. I'm planning an arrangement just as you describe. I have 3 switches/frogs I'd like to connect to one AR-1 and several I'd like to have 2 frogs to one AR-1.
I see no reason why it won't work.
Update. I tested the the AR-1 to see how it performed switching current for multiple frogs that cannot be crossed simultaneously, in my case I connected 3. The frogs were all attached to one RT output and then both. The AR-1 worked perfectly switching polarity as needed. While one frog was occupied another locomotive was run into one of the other frogs. This caused the PWR-56 to short out as was expected. Removing one of the locomotives restored the power. By being able to switch polarity of one or more frogs will save me using 8 additional AR-1s.

For us electrical morons, is this square wave DC idea attainable? Or is this our perpetual motion machine?

Awesome. And please don't mistake my comment for any form of lack of patience or irritation. This would revolutionize my modeling world and I was just sitting here over morning coffee thinking 'big picture'. I can wait a year or more if the concept works.
