The kernel of one of the greatest model railroads, the Gorre & Daphited, was only 3'-7" x 6'-8" to start. Not much larger than this, so who knows what may come of it?
Have fun with your trains
Welcome to the forums!
I am assuming you are modeling in HO. 3' is pretty narrow, as 18" radius track is the center of the track, thus needing at least 38" to keep it on the surface. There is 15" sectional track available or flex track could be curved to just fit, but you would be very limited as to what locos and rolling stock would be able to handle the tight curves. It would also put your tracks very close to the edge. A 40" piece would be better, if possible.
I have a 4'x6' HO layout and by using an offset scenic divider it makes it so the train can go somewhere. It has a passing siding on one side and a passing siding and a two track yard on the other. However, it I think it would be pretty tight if I didn't have the extra foot.
If you have N, then you have some room to work.
Good luck,
Richard
