I had a bit of bother with switching the three way points initially. Took me a while to realise the problem as they wouldn’t reliably throw.
I had them connected to some salvaged lenz accord deciders LS150’s and after a bit I realised they was not powering the motor correctly and shutting down one side of the solenoid output so no throw in one direction. Tried messing with various settings but didn’t improve so on a whim I bought a DCC concepts Ads4sx accessory decoder and straight out the box wired in and no problems at all. Worked perfectly so far!
Both Three way points now throwing reliably to my relief lol as I want the computer to switch them directing traffic to the appropriate storage track
