The Abtus ABT4670 Switch and Crossing Confirmation Gauge has been developed specifically for the undertaking of dimensional checks within the moveable part of a switch unit. Constructed from hard-wearing GRP and Nylon, the S&C Confirmation Gauge is electrically nonconductive, making it suitable for use in areas of 3rd and 4th rail electrification and will not interfere with the track signaling circuit.
The gauge measures the following parameters:
Free-Wheel Clearance (FWC)
This is the dimension between the running edge of the stock rail and the rear face of the adjacent switch rail.
Free-Wheel Passage (FWP)
This is the dimension between the rear face of an open switch and the running edge of the closed switch.
