Advice on Insulated rail joiners

[Thomard1]

I am new to all this and not very electrically minded. I need help on if/where to insert IRJ’s on a basic Hornby double track and siding,with points on all tracks. The power supply is via a Gaugemster type D double controller.

I have plastic rail joiners if I need to use them. Can someone advise ( via a simple diagram) , if possible,where they would need to be placed. Any help would be great. Thanks.

Theoretically you shouldn't normally need any IRJs with Hornby points as they are self isolating "dead frog" points but you are best to fit 2 IRJs between the two points that join the inner loop to the outer loop to prevent interaction between the controllers connected to the two loops.

The 2 IRJs are marked in pink.
