A telescoping rail for an X-ray detector drawer, which rail has at least three rail elements movable relatively to one another, namely a basic rail element, an intermediate rail element that is displaceable relative to the basic rail element, and an end rail element that is displaceable relative to the intermediate rail element. At least one driver is disposed between the rail elements. the driver is pivotably supported about a shaft oriented transversely or in inclined fashion to the displacement direction of the end rail element, and as a function of the intermediate rail element having been displaced out of the basic position, the driver is pivotable about the shaft into a slaving position which displaces the intermediate rail element along in the direction of the basic position until the basic position is reached, as a function of a displacement of the end rail element. As a function of a displacement of the intermediate rail element, the driver is pivotable past the basic position, out of the slaving position into a fundamental position which does not displace the intermediate rail element along. Moreover, in the fundamental position, the driver can enter into mutual engagement with the basic rail element so as to firmly hold the intermediate rail element in the basic position.
