  • Electrically operated railroad switch machine
    Patent number: 6568641
    Abstract: 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.
