What is the recommended center to center spacing for HOm tracks? This is for straight sections through a station siding and a double track bridge. I realize this must be wider on curves. Also how wide should my roadbed be? I am using N scale cork roadbed and I think I should add about 1/8" or 3mm strip to widen it. Is that about right? And one more question before I start cutting the plywood baseboard, how wide should it be to allow for mounting catenary? I will not add catenary until most of my scenery is finished.
Thank you,
Kevin Miller
