To go in and around the rails of my street track I thought I’d create a quick template. The idea here being to tape the template down to my work surface then tape a sheet of styrene smaller than the template to the template itself. Then I’d be able to use a the lines from the template to help me to line up the steel straight edge I scribe against. Looking at shots of brick/cobble-paved trackage in Halifax and Nova Scotia it sure looks, to me, like they fit about 5 full bricks between the rails. It seems that in N scale we always make things a little larger so I tried scaling that dimension up about 20% and find that they do in fact, to my eyes at least, look better.
