Hi joe123 & welcome to the site, you'll get lots of helpful suggestions & ideas on here, your plan for a 10 x 3 doesn't give you a lot space but as Glenderg & Dave's suggested a 1st & 2nd radius may work & by using flexi track you may !! get away with it, at the end of the day trying these ideas / suggestions out is the only way you'll find out. I did have track (1st & 2nd radius )on my dining room table number of years past & ran some loco's, co-co diesels & steam, it was not permanent or perfect & certinately as a layout it was not, but it worked & I got lots of pleasure from it,even if was only for a week ! keep us posted on your progress, PS I did not have any flexi track on this ! btb
