Displayed Below is the Final Design for the layout. It consists of a double track mainline, with a heritage branch line in dark blue on the inside and a shunting yard in light blue. This is all designed to fit on a 3" by 4" board. All track is Peco, with the outer line using 3rd radius curves and the inner mainline using 2nd radius curves. this means I can generally run whatever rolling stock I want.
