Abstract: A cross-over between tracks (1, 2) for track-gripping, track-bound vehicles consists of two parallel adjacent movable track elements (3) coupled to each other by several connection elements (4) of constant length. The track elements (3) can take two or three defined positions and allow changing from ne track to another without altering the track gauge. The connecting elements can be actuated by a common driving unit.

Abstract: A rail switch point element for a track system has a longitudinal axis of rotation and is rotatable about the axis to selectively switch between a straight ahead and a turnout position. A first straight track piece has first and second orthogonal planar surfaces extending in a longitudinal direction. The first surface is a tracking surface when switched to the straight ahead position. The axis of rotation extends longitudinally through the first straight track piece. A first curved track piece has a curved surface fixedly attached along an edge to the second surface of the first straight track piece, and has a bent planar surface orthogonal to the curved surface. The bent planar surface is a tracking surface when switched to the turnout position.
