"IF" we ever do have a yard.

  That will be up to the B.O.D. to decide.   It all depends on how reliable those large radius switches are.  I don't have any myself.  But, if we ever decide to have sidings, I think the added operational aspect would be fun. And it would be easy to understand.   I show a signal light connected to a toggle switch and a block of insulated track on each siding.   Assume trains travel toward the left on tracks 1 and 2,  And they travel toward the right on tracks 3 and 4.  By throwing the toggle switch so the red light comes on will cut off the current to the block and stop the train as it approaches the red signal.  Otherwise the light will be green and the train will travel straight through.  I think we would want to drill some small holes and put our wires under the platform.  If the switches are manually operated, then we will probably need a "Yard man" and the toggle switches should be out in the yard area, otherwise they can be in the control area. 
  By drawing things out, it helps to see potential problems easier.  For example the insulated block should probably extend all the way to the end of the siding in case we have a long train to park on the siding and we want to move it forward a little after it stops.
 Anyway, it does not cost anything to think about it.
