I have two 3 rail mainlines which I usually leave run on their own like a fish tank, each with two reverse loops. Of the four Ross switches involved there are no switch machines at all. Each train throws the points when it comes into them and that routes the train when it comes back. No derailment problems at all.
My three level 2 rail walk around the wall layout on levels 2,3 & 4 have 105 turnouts. Some of those turnouts are Caboose thrown, some Tortiose, however over 80 of the point pairs are only finger thrown as needed. Being dcc friendly there is no shorting. Also, no derail concern because the first axle of either a caboose or an engine corrects the points from a frog approach. My finger sets the points for a point approach.
Being too busy has it's own rewards. I have a case of Tortiose and drawers filled with Caboose hand controls but not have needed them. May never need them.
