The 2270 has its motors fixed to the turnout, they are not detachable like the other K track turnouts. I am sure it could be done though.

However there is no reason to convert it to servo drive because once you bridge the limit switches, the Marklin solenoid motors are 100% reliable. I did this to all my K track turnouts in storage yards and have had 0 failures in 6 years.
I did convert my K track turnouts for servo drive on the visible areas of my layout, though that was purely for aesthetic reasons only. Since yours is also in a fiddle yard then I see no reason why you'd do it.

Thanks for the help guys.

I like the slow motion of the servos rather than the snap of the solenoid hence my inquiry.

In the none visible area of my layout I am using c-track with Viessmann motor. I guess I will try to avoid the 3 way then in the k-track area.

Ah sorry I mis-understood, you wanted servos mounted underneath but your fiddle board is visible.

In that case yes I can see you wanting to go with servos. You're only option is to remove the solenoid motors and see how the mechanism works so you can attach a servo rod through a hole.
It's all custom work but I have no doubt it is possible.

What I've found with the micro switches, if you solder them to the solder points with too much heat they lose the spring action and it looks like Märklin hasn't discovered this as yet but I agree get rid of the solenoid switches and install servo motors, the other benefit with servo motors is when the power is off, the arm can't move whereas with solenoid switches there is nothing there to prevent the arm of moving., the same goes for me for the switchen tracks, another disaster area in the making.
