Read a ton of threads on the topic of yard track spacing and the vast majority like 3.5" CTC. In working on new layout mockups (and using RR-Track ver. 4.02) it appears that the Ross 200 / 201 switches (#4 at 14 degrees) provide the 3.5 spacing. I was also able to check the roughly 3 inch spacing and it appears the #100 / 101 ( #5 at 11 degrees) provides that if someone wants it. Several in the past threads noted a 4 inch CTC option but I don't see a straight switch to accomplish this, without space consuming use of the transition pieces . Did I miss something?
Here are the #4 and #5 versions from RR-Track (#4 on top and #5 bottom).
