Apparently the 3562-25 is one of those "oddball" operating cars requiring special attention. I found this OGR thread that suggestd Lionel provided a special operating track section just for this car. As highlighted below if the car is used on a "standard" UCS that you should position only one of the operating shoes on the UCS operating rails.
So to your point, I guess you could remove one shoe if your layout has already been "permanently fastened" to expect the loader to function at a specific position. Else I suppose you could "offset" the position of the operating point so that only one shoe falls on the trigger rail. I think I've managed to confuse myself ... not sure I'm making any sense!
