I had bought a pair of GS-1502 linear servo for steering in a HO scale car. If they work from Deltang P pads I think I may solve power problem to operate the coupler. Magnetic actuators are a wee bit smaller than the linear servo. All of this is an experiment at this point as I have never done this before. I have only used P pads for LEDs.
GS-1502 Linear Servo under consideration.
