SABORAGE-RESISTANT SWITCH DEVICE FOR MOVING RAILROAD SWITCH POINTS

The switch machine disclosed uses electro-hydraulic power to move the throw rod against the resistance of redundant mechanical springs and the switch point, for half of its stroke. Once the switch points have moved past mid-stroke the spring force in the machine is released and assists in the closur...

Zusammenfassung:	The switch machine disclosed uses electro-hydraulic power to move the throw rod against the resistance of redundant mechanical springs and the switch point, for half of its stroke. Once the switch points have moved past mid-stroke the spring force in the machine is released and assists in the closure of the switch points against the stock rail. All hydraulic force is removed when the power unit is turned off. The redundant spring assembly holds the switch points firmly against the stock rail with 2000 lbs of holding force. This machine can be described as a power operated spring switch.
