I am nowhere near the point of wiring my layout (haven't even put down the first section of track, had no time) but I am mulling over something. I have #6 ross ready switches with dz1000 switch machines (2 pairs, to be used on 2 separate crossovers), and a #11 switch as well. In the Ross documentation they mention that some engines, with close or only 1 roller, can have problems on it. Most of my engines probably would be fine (mix of post war and modern conventional engines), I could see maybe a couple of RMT engines I have having problems.  The recommended fix is to use a relay to power the frog, my question is have people found it worth the effort? Does it make regular engines go through easier? I am not worried about the cost (I don't have that many switches that would likely need a relay, maybe 5 of them), for me it is wiring them in when wiring isn't my favorite thing. If it will improve overall importance I will do it, if it is for a couple of balky engines I likely won't run much I may just leave them as mostly shelf queens.

Actually, your #6 switches will likely need the relay switching to accommodate many locomotives.  I don't know of any engines with one roller, those would stall on virtually every switch on the planet, I've never seen a switch that doesn't have some kind of gap in center track coverage.  I'm not sure what a #11 switch is, are you talking about the Ross #100/101 Regular 11 Degree Switch?  Those are less troublesome, I don't have relays on those and most of my stuff makes the transition.  I also have the 14 degree 200/201 switches, those are no problem as well.

Thanks GRJ, yeah it is the 11 degree switch. That is the kind of advice that is valuable, I'll order the relays so I have them when the time comes to wire this.
