A railway switch mechanism including first and second switch blades, wherein a switch point of each of the first and the second switch blades is vertically displaceable by means of a displacement mechanism in order to establish a switch movement in the respective switch point, wherein the respective displacement mechanism includes at least one pair of cooperating wedges having a lower wedge and an upper wedge, wherein at least one wedge of the at least one pair of cooperating wedges is arranged to be displaced in a direction substantially parallel to a longitudinal direction of the switch blade or parallel with a longitudinal direction of the switch mechanism, and wherein the switch blades are elastically deformable in the vertical direction or pivotally connected by hinged joints to first and second closure rails respectively for enabling the vertical displacement of the switch blades.

The disclosure relates to a flexible switch element for a track carrying rubber-tyred trains comprising two parallel rails each having an upper running surface for the tyres and an inner side surface for supporting a continuous strip (B) for guiding the train. The switch element has at least one hinge providing the longitudinal link with an adjacent switch element. The switch element also has a set of longitudinal abutments engaging, on the one hand, with the hinge in order to adjust the relative angular orientation of the element and, on the other hand, with a pivoting bottom rod providing the connection to and the alignment with an identical switch element arranged symmetrically on the opposite side of the switch. The disclosure also relates to a track switchgear comprising the assembly of such elements and a method for transporting passengers along a track provided with said track switchgear.

A turnout includes a fixed beam, and a first and a second movable beams respectively on two opposite sides of the fixed beam. The fixed beam is arranged on a turnout platform. The first movable beam is movably arranged on the turnout platform between a first and a second positions. The second movable beam is movably arranged on the turnout platform between a third and a fourth positions. When the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage; when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage.

The present invention provides a movable point frog. In this application, quasi-continuity of rails is achieved at the frog, so that a gap in the frog is eliminated, vibration and noise are reduced, and transverse impact of wheels is eliminated. Guard rails do not need to be disposed. The frog itself does not limit the speed of a train running on a main line and a branch line. Therefore, the train running on the main line can pass through the frog without reducing the speed. A relatively small curve radius and a relatively large frog angle may be adopted for the branch line. Compared with integrally cast frog equipment in the prior art, all the components in this application are detachably connected, and therefore can be simply mounted, easily maintained, and produced in batch.

A railway points arrangement 10 for a railway track junction comprises at least first and second pairs of longitudinally-extending, parallel-spaced static stock rails 12, 14, defining respectively a first route and a second route, and a pair of longitudinally-extending, parallel-spaced switch rails 16 which are movable between a first position in alignment with the first pair of stock rails 12 to select the first route and a second position in alignment with the second pair of stock rails 14 to select the second route. At least one of the movable switch rails 16a cooperates with at least one stock rail 12, 14 of each of the first and second pairs of stock rails 12, 14 when the movable switch rails 16 are in the first and second positions, and the at least one switch rail 16 and the at least one stock rail 12, 14 are shaped to define a mating profile 50 which aligns the switch rail 16 and stock rail 12, 14 and prevents transverse movement of the switch rail 16 relative to the stock rail 12, 14.
