Stacking masonry block system with transition block and utility groove running therethrough

A masonry block system comprising:

• a plurality of blocks, configurable in a stackable row, each of said plurality of blocks having a top surface and a bottom surface, wherein said bottom surface of each of said plurality of blocks is configured to match with the top surface of each of said plurality of blocks, wherein each of said plurality of blocks contains a cavity such that said stackable row has a vertical opening therethrough;
• and
• a starter rail, configured to mate with said bottom surface of each of said plurality of blocks and configured to be in communication with said vertical opening, said rail including at least a first longitudinal planar surface and a second longitudinal planar surface longitudinally connected to the first longitudinal planar surface, wherein an angle between said first longitudinal planar surface and said second longitudinal planar surface is acute and forms a void when one of the said plurality of blocks is placed over said starter rail, wherein the first longitudinal planar surface is co-planar to a base of the one of the said plurality of blocks when the one of the said plurality of blocks is placed over said starter rail, and wherein the bottom of said void has a larger width than the width of the vertical opening, such that when hardenable, flowable material is poured into said opening and void of said starter rail, movement of the blocks is prevented;
• a channel located proximate said top surface, said channel extending throughout said plurality of blocks;
• and
• wherein at least one of said plurality of blocks has a third surface configured to mate with said top surface to form an intersection.
