摘要:
The invention relates to a prestressed concrete sleeper, having at least two sleeper sections that can be coupled or are coupled rigidly by a connection device embedded in the sleeper heads, wherein the sleeper sections each comprise a concrete in the region adjacent to the connection device which has a higher rigidity than the concrete in the other regions.

The invention relates to a switch and to a method for transporting and installing such a switch, which is equipped with longitudinal sleepers, the sleeper sections (2, 3) of which are or can be coupled in a flexurally stiff manner by means of a connecting device (16) embedded in the sleeper heads (4) so that the switch can be folded for space-saving transport. The divided longitudinal sleepers are oriented relative to each other and installed in such a way that the joints of the longitudinal sleepers are aligned along a straight line, which thus can serve as a rotational axis for folding up a side of the switch. The joints aligned on the rotational axis act similarly to a hinge band so that complete switch segments, such as a switch end part or the core region, can be folded along said line.
