Overview 

 

Abtus track gauges have been designed with a sprung gauging foot, with all measurements 
displayed on the useable end of the gauge, ensuring improved repeatability and accuracy of 
measurements, whilst minimising potential for user error. 

Constructed from hard-wearing glass reinforced plastic (GRP) and polyvinyl chloride (PVC), 
the ABT4550 is electrically non-conductive and will not interfere with the track signalling circuit. 

These therefore are suitable for use in areas of 3rd and 4th rail electrification. The ABT4550 
is  available  in  both  imperial  and  metric  versions  for  multiple  track  widths.  The  standard 
mushrooms measure 14mm below the top of the rail (TOR), alternative P-points should be 
specified when an order is placed. 

Super-Elevation is measured electronically and is shown on an LCD display. The expected 
battery-life for normal, average usage is 12 months. The unit is powered by 2 standard 9v PP3 
battery which can be easily by replaced by the operator when required. 
Track Gauge is measured mechanically with readings displayed through a clear polycarbonate 
window on a linear scale.
