Uh-oh....as I had Marx trains as a kid, is it true that most modern trains will NOT run well on 0-27? I do not like it now and want more realistic track, and I have never liked the profile of "Lionel" "O gauge". Which is why I am still wishing for a better track system ((more realistic, with a better (low) profile, but simple to use)). The nonelectronic stuff I run seems to run okay on O-27, and I thought I remembered that K-Line made that 0-27 profile in a variety of radii, etc.?
This is not just a question of minimum radius, is it...that modern trains won't run well?....a Triplex is obvioulsy not going to ride around a 27" figure eight, but I am guessing that, a Challenger, or whatever runs okay on MTH Scaletrak, with its lower profile.
