Best to test unless you run NMRA standards. Post war and/or tubular? I'm not sure that is there. It's pretty scale minded, especially today.
Each ...... ( Goofle glitches if I connect these lines of type)
engine/car has overhang in a curve. It may be the pilot, steps, cab roof, or toolbox/tank in the middle that will hang up. Some steam cabs really kick to theoutside wide up high, diesels & electrics it's usually the pilot or frame, steps & rails. Toolboxes hang to the inside of curves (along the stringline path between trucks.)
The tighter the curve the more overhang. The overhang also extends past the curve and onto straights an inch or three at the exit (if you only run one direction you can sometimes have a narrower entrance clear into curves a bit.)
My biggest offenders are a Berk cab roof up high, an E-33 front rails at frame height, a General or Hudson at the pilot. And any tool/tank only hits 0-27 turnouts. On 0-27 I use a 2" portion of a rough cut 2X4 scrap (rough cut is larger than a finished 2x4) with a piece of hardboard/paneling stacked ( my go to for grade shims).... so about 2¼" on 0-27 and 1¾" on 0-36. Set up something kinda soft to knock over and run everything you have by it, facing both directions 
And leave a little space for twisting or shifting laterally, and backing as you get shifting there too.
