I have a 12889 Windmill accessory from Lionel. General concensus I found is it just doesn't work. I decided to take it apart and replace the vibrating coil with a N20 series Geared DC motor. Just took 3 3D printed parts to work in the space available.
This is the motor
Motor Adapter back
simple Gear box cover
And a shaft adapter
The finished product is hard to distinquish from the original
Full details coming in the 3D print catolog.
Will use a buck convertor to go from 14V ac to the DC voltage needed for the motor.
