Wiring a Single Point so it is DCC Friendly

The diagram below shows, initially, a point in mid throw.
Move your cursor on and off the blocks below left to see the effect of switching the point.
Note that each colour represents an electrical section of the point.
If the switches, S1 & S2, are not present and the switch blades aren't touching the stock rails
then there will be no connection between the sections.

This idea of wiring a point to make it DCC friendly was devised by Andy Reichert and is reproduced here with his agreement.
Further info can be found on Andy's website
And specific details of this idea are here
Note that Andy's site is P87 (HO scale to P4 standards), however his ideas on wiring are equally applicable to all gauges.
