I'm trying to figure out from the ROSS diagram how to hook up the DZ-1008 relay(s) so the diamond "short rails" will alternately switch from "hot" to "ground" so our short-roller engines won't stall out on it.
The instructions seem to indicate only one relay will accomplish this but I don't see how that will work with one ... I'm missing something here ...
Help will be much appreciated!
Thank you.

Kerrigan, I am looking at the instructions on the RCS website. I don't know that I can answer it, but what exactly is your question?

How does one relay, looking at the diagram, alternately heat one set of rails, while making the other set common, then reverse and make the other set of rails hot, and the other common.
On the three-way it took me two relays to accomplish the alternating.
How can I make it work with one relay when the output wires will only do it for one set of rails, not two sets.
The central diamond is kept hot all the time so it doesn't need to be switches; just the short rails on each side of the diamond.
A puzzle for this ole Irishman.
If you look at the wiring diagram, the Southwest to Northeast leg is fired by 1 button (which triggers the 2 switch machines). The Northwest to Southeast leg is fired by a 2nd button (which triggers the two respective switch machines).
Based on which button is pushed, the DZ1008 alternately powers 1 set of short rails (#1) or the other (#2).
The DZ1008's WHITE wire goes to short rails numbered 1 on the diagram.
The DZ1008's GREY wire goes to short rails numbered 2 on the diagram.
Track Power comes into the DZ1008 via the BLUE wire.
By the way, on a 3-way switch, you have 3 states or paths. That's why you need two DZ1008s. In a double cross-over there are only 2 paths (criss-cross and straight). That requires only 1 DZ1008.
Does that help?

Thank you G3750 .. I'll try it that way.
What makes the previously "hot' rails turn into commons when the relay flips? One of the problems is when those two short rails go dead, instead of going common. A couple of the small engines need the common as well as the hot. They stall when the two short rails are dead when a rubber tire is on the other track relying on the remaining wheel to be common but if the rail is dead it isn't ...

Sorry, I don't know the answer to that one.
