Im trying to decide on what track I want to use and I was wondering what the width of HO scale track is, but like not from rail to rail, I'm talking about the fake wood under the rail.
It would help to know what you want to get out of your track.
Do you want ease of assembly? What kind of engines and trains do you want to run on it? What kind of layout space do you have? A table of some dimension? How big? All of these play into choice of track.
In the railroad world, the fake wood items are "crossties." Or, in England and other parts of the world, "sleepers." Although in certain regions of the world where wood is scarce, crossties now are manufactured from concrete. I've even seen reports of crossties being manufactured from recycled old automobile tires.
