Described is a railway diamond that allows two intersecting railway lines to cross each other at-grade without incurring discontinuous miming surfaces, thus avoiding the large dynamic impacts normally occurring in traditional railway diamonds. Modified frogs with piston-mounted load-pads located at critical locations can selectively close the inactive flangeways, thus providing quasi-continuous running surfaces over said flangeways for the active route. Operation of the pistons is performed automatically through an interface with the rail traffic control system and provision is made for continued operation of the diamond in instances of technical anomalies. The operating mechanisms are located below the frogs, with risers providing the required vertical separation between the ties and the frogs. Benefits of embodiments of the invention are reduced maintenance costs, potentially increased line capacity, service life extension for the components and the diamond itself, as well as environmental improvements.

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.

An inner guide rail switch (100) and a rail transit system (1000) having same. The inner guide rail switch (100) includes a fixed beam assembly (1) and a movable beam assembly (2). Four passageways are defined by the fixed beam assembly (1). The movable beam assembly (2) includes six movable beams. The four passageways are switched through combined movement of the six movable beams.

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.
