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.
