A switch stand for a railroad switch permits the switch to be locked against unauthorized movement of the switch. The switch stand permits trailing operation, even if locked. Passage of the rolling stock through the locked switch is permitted by allowing temporary movement of switch points of the switch when contacted by wheels of the rolling stock. The switch stand can also be unlocked and the position of the switch points changed manually to an alternate position from the normal or set position and then locked against unauthorized movement of the switch.
