    There's no such thing as a minimum radius for a scale, only for given equipment in a given scale.

    An 18" wide shelf won't be able to accept more than 8" radius. This is very tight; the smallest radius usually available in sectional track (in the US anyway) is 9.75". However, European sectional track systems often do have curves this sharp. It's possible, with very careful equipment selection and testing.

    PECO's SetTrack №1 radius is 9"... but as stated, this will severely restrict what you can run on your layout...

    Hi!

    If you have a 18" shell, you can calculate another 3"-4" space you need from the tracks to the side of the shelf. That leaves you with about 14" of space for the curves.

    The tightest standard radius available (usually from european manufacturers) is 7.5". You can find these curves from Arnold Rapido, Fleischmann, Roco or Minitrix. Minitrix also offers turnouts with this radius, very nice for extremely small layouts.

    If you chose to use that kind of raduis, you will have a very limited choice on your locomotives and cars. Locos like Kato's SD70M cannot take this radius even running light. Body mount knuckle couplers will either decouple or derail the train, because they cannot be bend that tight.

    Of course you can use this raduis. I just tested a LifeLike FA on a 7,5" radius and 7.5" turnouts, it worked just fine. I guess most shorter LifeLike and Bachmanns will do, Arnold Rapido and Minitrix definitely can take radii that tight.

    If you use only shorter 4-axle locos and cars, it does not even look too bad. For save operations I would recommend rapido couplers, they can take these tight radii easer than any MTL can.

    The alternative would be building a point-to-point switching layout.

    You could always "balloon" the ends out to 24" wide, to give more turning room...

    Yup... per my last post, balloon the ends (the last 24&quot to 24" wide, keeping it 18" wide in the middle...

    I am going to go with a 24" by 72" space I will make a bench for that size.
