I scratch-build my diamonds/crossings and the two frogs (highlighted in pink in the attached) are electrically isolated by gaps in the rails. I can power them, and change their polarity, through the use of a toggle switch or Tortoise switch machine, but was wondering if a Ring Engineering AR-1 (Auto Reverse Module) can do that for me?
Would it automatically switch the polarity of an approaching train on either of the tracks?
