    摘要: A railroad frog assembly (10) is provided with a spring wing rail latch holdback subassembly (32) that continuously retains the spring wing rail (28) in a spring wing rail fully open position when activated by the wheels of a railcar traversing the frog assembly (10), and that automatically deactivates the latch holdback subassembly (32) and releases the spring wing rail (28) from retention in an open condition and for complete closing after the last railcar wheel has passed through the frog assembly (10).
