Pre-made resistive wheelsets are not something I have seen in Europe, I use SMD resistors, superglue and silver conductive paint.

I do the same here, make my own resistor wheels. There are several company's that do make resistors wheels in the USA.

You appear to be connecting to the global detector K to the buss bar, and from the DR5088RC outputs via shunt resistors to the buss bar but I cannot see where you are connecting the feedback's for the track into, unfortunately all I can see are a jumble of read and black wires coming from somewhere and going to somewhere – hence asking for a clearer logical diagram rather than a picture.

I did not show all the wiring because that does not change on wiring the DR5088RC, just adding the resistors is all I am doing.

?

I also assume that when you say “Resistor Wheels 4 x 10K (2.5K)” this means four axles, each of 10k giving a resistance of 2k5 across the track?

Yes
?
