I just read a thread here that said for IHC Heavyweights the minimum radius should be 22" to 24", with 30" being even better. He was having trouble with wobble (sounded like a combination of poor design and too small radius).
If you have these Kato Superliners (Amtrak Phase IV) - will they work OK enough on an 18" radius? Also - with a 1 1/4" track spacing on a double mainline curve (the outside being 18 3/4") - will they knock off a train coming the other way?
I don't have the passenger cars yet (although I own 2 of the Kato P42's), so I can't experiment.......
