Layout

[smife]

Trying to make a tabletop oval layout 20" wide by 40" long. Do they make a radius that can accommodate that in N scale.

[Bucksco]

The smallest radius Bachmann produces is 11.25" which makes a 22.5 " circle.
Try searching the internet for manufacturers who produce a smaller radius curve.

You beat me to it Yardmaster 20" wide? No. But 26" would work with that track.

You will need to stick to the smallest locomotives and rolling stock if you build a layout with
the tightest curves possible. I strongly urge you to give yourself more space for your layout
if you possibly can.
