Hi all,
A very subjective topic, but here goes.
Track that I consider to have a “toy-like” geometry:
Aristo (the turnouts that are R1 and/or have a radius through the frog), Bachmann, LGB, Piko, USA Trains (the R1 stuff)
Track that I consider to have a prototypical geometry:
AMS, Aristo (the numbered turnouts), Llagas Creek, SunsetValley, Thiel
Track that falls in between:
Train-Li
Those are the ones that come to mind right off the bat. I’ll add some more tomorrow.
