wiring a yard ladder?

Hi guys, I’m looking for some advice on wiring a 6 track yard using a 6 position selector switch (double pole I think, but not sure). I have it set up similar to this…

/----- 1
/-d------ 2
/-b--------- 3
–a----c------- 4
-e---- 5
-– 6

I’m looking for a way to control this so that selecting track 1 will move points a, b, & d only,
track 2 moves points a, b, & d only as well but with d flipped the other way, etc…

Any help would be appreciated.

Without knowing the exact nomenclature of the switch you have, it’s impossible to offer advice. What might be a better choice in your case is a diode matrix circuit.

Perform a couple of Google searches for a diode matrix and you can come up with examples, such as:

Sorry, I forgot to mention that I’m using tortise motors to switch the points…
