The decal tool in SplineTrackmaker only do lines and dashed at the moment. For grid decals Bink is doing a very good tool. Is almost ready and will be available soon. EDIT: My Boolean tool (MMtool box) can create decals but you need to create the object solid.
Thanks For road lines don't create all line for large tracks. Is better split the lines (detach) is faster and have more control.
