3 position Servo Control by DCC

[ngtrains.com]

I am looking for some help with controlling a turnout servo that needs to stop in three adjustable and remembered positions when controlled by DCC

My 0n3 engine terminal layou has one of these outside the engine shed

 

 

Hopefully you can see the issue. Three possible positions, each needing initial adjustment that is then remembered and repeatable and working as part of route setting on DCC.  The plan is to have some automated movement of engines, geared locos mainly, shuffling around the yard so the DCC and automation need to be able to control it.

 

Is there an accessory decoder that can control a servo to 3 positions?

 

I have found a circuit board online that would do it but its not linked to DCC. It has 3 buttons, one for each route. You set position one mechanically, and then positions 2 & 3 have pots to adjust them. I guess another slant would be a DCC way of effectively pushing the three buttons.

 

I've done DCC in my loco's for years but never connected the points to it prefering the mimic panel but the idea of some automation means the turnouts need to go DCC

At the very bottom of the page is a 3 way stub point which they say has been controlled using the kit on the page.

It certainly does. Thank you.

I never thought to look at Tam Valley despite having one of their frog juicers set aside change the frog polarity on the layout
