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

摘要： A switch machine for moving railroad switch points. The switch machine includes a switch stand adapted to be connected to the railroad switch points. The switch stand includes a rotatable hub which is selectively rotatable to throw the switch points. A rotary actuator includes a rotatable pinion that is coupled to the hub of the switch stand. A hydraulic pump and a valve are in fluid communication with the rotary actuator and selectively control the direction of rotation of the pinion. A first proximity sensor and a second proximity sensor are provided to sense the position of the pinion and hub. When the pinion and hub are rotated to a first position to move the switch points to a first switch point position, the first sensor will deactivate the hydraulic pump. When the pinion and hub rotate the switch points to a second switch point position, the second proximity sensor will deactivate the hydraulic pump.
