R-09 are the same curves in blue. Sets wise I'm not too sure. The only time I'll use these curves is when one portion of a ready made layout has problems connecting to an irregular part of a layout, also a good curve to substitute the double track curves if you don't have these.
Those piers are designed to work with the elevated rails as the middle plastic piece is a filler for those gaps the elevated rails make. Unfortunately lacks overhead line holders or signal holders. The only ones with these holders are the grey version of the yellow block piers and the old piers with double convex joints (although shorter in height).
