Question. I am laying down a 4 track passenger yard and would like to keep the tracks spacing as close together as possible.
I run 21.5 inch cars (Atlas being the longest car), and a Lionel PRR S-1 6-4-4-6 which leans out pretty far over any radius.
As I turn a 90 degree corner on the layout the sharpest radius will be an 072 inch. What should be the corresponding 3 track radii and track spacing on the outside of this radius so I do not have a touch condition?
Thanks,

I can tell you on our Modular club layout, we have 081/072 w/ 4.5" spacing. We have no problems with 21" cars on the curves.

Thanks Gilly. So 072, O81, then... 090 and 096?
I would add an inch between the 072 and 081. We have had side swipes with big equipment between this pair. Going wider, you should be fine with 4.5" center to center.

Point of contact: usually articulated engine on the inside curve, longest car on the outside curve. Your experience may vary.

Hey thanks Chris, I will start with 5.5 between the smaller radii, I take it the next radius say 090 can be lest than 5.5? And the next one after that?
Once you get wider than 081, you should be OK with a 4.5" center to center spacing, as the overhang gets reduced.
You can always layout the track on a temporary setting with whatever radii you want and place the suspect equipment on the track to see how tight things really are. It does not have to be fancy; rather just enough to answer the "Go/No Go" question.
