摘要： 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.

摘要： 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.

摘要： Rail system for an electrical pallet conveyor system, having a switch point which is arranged between a main track and a plurality of secondary tracks and which includes a plurality of moving rail sections. Depending on their position, the rail sections are able to connect the main track to the secondary tracks. The moving rail sections which are associated with one rail of the main track are in this case mounted on a first moving slide, and the moving rail sections which are associated with the second rail of the main track are mounted on a second moving slide which can move independently of the first slide. A dedicated drive which can be separately actuated by a control device is associated with each slide.

摘要： A spring rail frog includes a movable wing rail, a fixed wing rail and a nose rail. The movable wing rail is provided with a bendable portion and a non-bendable portion. The bendable portion can include any or all of a reduced width base portion, a reduced width head portion and an increased width web portion. The height of the movable wing rail can also be smaller in height than the height of the nose rail. A fixing plate can also be provided between a base plate and the movable wing rail to adjust the relative height of the movable wing rail and the nose rail. The movable wing rail extends beyond a spacer block disposed between the movable wing rail and the fixed wing rail. The movable wing rail extends away from the nose rail a predetermined distance for connection to the lead rail.

摘要： A crossing frog with moving point (1) for very long railway switches incorporated in long welded rails, comprises a cradle (2) in two elements (3 and 4), one molded and the other not molded. One element (3) is of molded steel, of which at least the two ends (3A and 3B) on the point side and the two ends (3C and 3D) on the heel side are shaped as a rail profile. However, only the rail profile of the two ends (3A and 3B) effectively serves for rolling, the non-molded element (4) being mainly made up of parts (5 and 5') produced integrally as rails and connected to the two ends (3C and 3D) on the heel side of the molded part (3). Neither the rail profile of the two ends (3C and 3D) nor the rail profile of the parts (5 and 5') effectively serves as rolling surface, the moving point (1), for its part, being produced integrally as rails of which all the upper faces effectively serve as rolling surface.
