PROBLEM TO BE SOLVED: To provide a track carrier system in which a difference between the calculated wiring length of a communication line and the actual wiring length is reduced, and the disposed communication line is easily extracted. SOLUTION: This system is constituted of a track, a track carrier for carrying an article along the track, a communication line 6 where a pair of wires 61 are coated by an insulating member 62 in a parallel state, and a communication line support part 95 set along the track for supporting the communication line. The communication line support part 95 is provided with a pair of wall faces 951 disposed so as to be faced to each other with an interval with which the communication line 6 can be inserted into the parallel directions of the wires 61 and protrusions 952 continuously or intermittently formed along the longitudinal direction on at least one wall faces 951, and protruded so that the vertexes can be fit between the pair of wires 61.
