Re: AR Vs Tortoise to power frog

 

I always use switch machine contacts to control frog polarity on turnouts and haven't had an issue. On my layout I mostly use Bluepoint machines, but Tortoises work the same way.

I also use DPDT relays controlled by switch machine contacts for reverse loop polarity. I don't plan on ever having any AR circuits on my layout ever, at any time, or in any location.
