So, only having 38" max space ive been running a 2nd radius oval ( 00 gauge )
I wanted to run more than one loco at once so i put in an inner 1st raduis oval. Most of my stock runs round it perfectly fine. Pretty much all diesels including the new Bachmann 47s 24s 20s. The new 37 however derails. Even the accurascale 37 and the siphons are fine on 1st radius.
This has got me thinking tho, does running on track below the mnimum recommended radius cause damage?
