A check rail arrangement for a switch or an intersection, the arrangement including a grooved rail (16) provided with a grooved rail head (14), a groove (18) and a lip (52), and a check rail (12) which is supported at least on the lip and is arranged by a fixing mechanism in such a way that it can be displaced in relation to the grooved rail. The aim of the invention is to be able to easily displace the check rail. To this end, a fish-plate block (40) extends from the grooved rail (16), the fish-plate block including a longitudinal groove (42) which extends perpendicularly to the longitudinal direction of the grooved rail and in which a slot pin (44) engages in an adjustable manner. The slot pin can be tightened by a screw (46) extending from the check rail (12).
