Overhead rail saws are generally the more expensive of the two. They are common in production environments, as you are able to cut and work at a comfortable standing level. Some examples are the Imer Combi 3000 and the Felker FRS-51.

Track saws are an economical choice, and have the advantage of being able to cut very large pieces of stone. The track is placed on the slab, and the blade is run along a track. The Master Wholesale SlabMaster and the Felker Trackmaster are two popular track saws.
