I got to thinking on everyone's comments on track spacing. Just like the 2R use of radii and the 3R use of diameter, seems to me the same thing is happening here. With my Ross track (and I presume its the same for all mfgs) when I said 6 1/2 inch center rail to center rail, this is the same as saying 5 inches outer rail to outer rail. Of course saying 5 inch spacing really doesn't convey what is really going on. NMRA uses track centers as their references and of course radii. Hmm, what does "between tracks" mean?
