How could I provide power and/or data coupling between train cars?

That's quite impressive!  But if I got it right you'll need a servo motor in each car that you want to be able to decouple ?

That is correct.  Some modelers either use magnets (permanent or electro) mounted strategically under the track to actuate the magnetic trip pin in the couplers to uncouple cars.  However, most modelers just use a wooden skewer or pencil to manually open the coupler knuckle to decouple cars.  This is acceptable because in the real world train cars are manually decoupled.
