So all the points on the previous incarnation of Abbotswood had Tam Valley frog juicers. On the current layout they are only used on diamonds and reversing loops. They are solid state not relays.
We are totally DCC sound … and there are zero issues with them, they do their work without any indication they are there … polarity switching instantaneous. Take a look at layout videos in signature to see them in action … but you won’t notice them!
