QUOTE: Originally posted by n2mopac This question depends on a lot of things--the type of railroading you are doing, the era you are modeling, the length of rolling stock you will use, etc. I model N scale in the modern era and I use18" min radius on the main line and 12" on industrial sidings, etc. The is what I would consider minimum--wider curves (22" or larger) look even better on the main. Technically you can run as small as 9" or 10", but I do not recommend it for looks and operational purposes, especially with any roling stock over 45 scale feet in length. Ron
I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
