Seacoast posted:Hi Mark, this is 2 rail O the larger the steam engine with fixed drivers the larger the curve, 8' diameter might work I don't know about 6' diameter. 3 rail this would work with no issues, 2 rail is a different beast.
Davy, 10' would be better. Give it a try with your current curves & see how your engines work.
Thank you George! Yes 2 rail is a different story.
