The present invention shows a telescopic rail having at least one inner, middle, and outer rail element, wherein the inner and outer rail elements are each longitudinally displaceably supported at the middle rail element over rolling members that are guided in a rolling member cage. Provision is made in accordance with a first aspect that the rail elements are mechanically force-coupled via a rail synchronization arrangement such that on a longitudinal displacement of the outer rail element with respect to the inner rail element, the middle rail element is longitudinally displaced with respect to both the inner rail element and the outer rail element. Provision is made in accordance with a second aspect that at least one rolling member cage, and preferably both rolling member cages, is/are mechanically force-coupled to at least one of the rail elements via a respective rolling member cage synchronization arrangement such that a longitudinal displacement of the middle rail element with respect to the inner or outer rail elements results in a longitudinal displacement of the corresponding rolling member cage with respect to the middle rail element.
