Abstract: A railway switch stand includes a reciprocating toggle arm which extends from the stand to operate a railway track switch between open and closed positions. The toggle arm has one end connected to a block which is operably mounted on the switch stand base for reciprocating forward and rearward movement. Forward and rearward brackets on the base prevent movement of the block beyond predetermined forward and rearward positions. An hydraulic cylinder connected to the block selectively moves the block between forward and rearward positions so as to reciprocate the toggle arm and throw the track switch. A pair of throw arms are pivotally disposed on opposite sides of the block relative to the blocks reciprocating path, with a forward end of the throw arm connected to the block.
