Someody tell me if I'm right on this. You have two parallel tracks and a slip switch between them that allows you to either stay on the track you're on or go onto the other one.
With a single slip you can only change tracks if you are coming from one direction, with a double you can do it coming from either direction.
If you 'roll your own', using 4 turnouts and a crossing, you have a double switch, right?
