Gauge Clearance Surveys

Working to Network Rail Standard NR/L2/TRK/3203 and using cutting-edge laser measurement equipment, we deliver the profile and vital clearance information your railway projects so desperately need.

Whenever changes are being made to track, surrounding infrastructure or rolling stock, design consultants and railway contractors must ensure there is adequate clearance for trains to pass safely.

Gauging surveys

By using the very latest LaserSweep and Abtus RouteScan instruments, our specialist gauging teams can produce supremely accurate profiles of all manner of structures, from tunnels and platforms to bridges and OLE gantries.

For more complex structures, we can combine one of our Trimble GEDO track measuring trolleys with an HDS 3D laser scanner, producing detailed models to aid in the design process whilst also collecting valuable cant, gauge and geometry information. Where required, a calibrated platform gauge will be used for platform gauging and lower sector structures.

Using ClearRoute software, our delivery team can accurately determine the distance between trains and surrounding structures, supplying profiles in .SCO format (or tailored gauging reports) for use by design engineers. Critical to ensure that designs remain compliant once constructed, the structure profiles generated thanks to our gauge clearance surveys prevent clashes between trains and potential obstacles occurring (such as signals, girders and so on).

Not solely for design purposes, we can also carry out post-construction gauging surveys to verify the as-built position of various key elements.
