The underfloor rail delivery system has an underfloor rail (10) with at least two hollow sections (22,24) spaced at a distance from each board, between which a longitudinal duct (64) runs. Current conducting bars (40) are provided at the two side walls (32) of the duct. Guide plates (54,54.1) project laterally from both sides in the duct, at which the hollow sections are so fixed, that they leave bare a narrow longitudinal gap (58) between them. The guide element is positionable with the longitudinal gap between the two guide plates.
