Model 953 Electric Switch Lock

Wabtec Positive Train Control PTC Electric Switch Lock

The Model 953 Electric Switch Lock prevents unauthorized and unwarranted operation of switch stands, hand throw switch machines, derails, and other devices. This is done by using a plunger that is lowered into a hole in a lock rod, preventing motion of the attached devices. The unit may be electrically interlocked with the signaling system or remotely locked by the dispatcher, preventing switch operation unless traffic conditions allow safe operation.
