ABSTRACT:
A manually-operable railroad switch stand for causing movement of railroad switch points between two extreme operating positions is provided with a crank assembly that is connected to the switch stand input shaft for joint rotation and that has a pair of parallel and substantially laterally spaced-apart handle pull-push segments which are each of sufficient length to alternatively accommodate an operator's hand or an operator's foot and which each may be selectively hand-grasped or foot-engaged by the switch stand operator without having to significantly bend his/her spinal column at the waist when manually causing movement of the switch points between the switch extreme operating positions thus avoiding possible costly operator spinal injury.
