Title: Concentric ovals
Post by: shieldsadvert on August 25, 2026, 11:20:30 AM


I have a 22"radius ho track oval with three straight pieces and one 3" piece on each side. I want to connect them in a concentric oval using a single atlas manual switch and 18" radius track for the inner oval. How do I do this?

Is it possible to achieve a consistent distance between the outer and inner tracks without using flex track?

Thank you,

William

If you are using all Atlas track you could do something like this:

It can be done with EZ-Track, but the fitter pieces will come out different because of slight differences in the geometry of the switches.
