PBH Surveys’ provide structure gauge clearance surveys in compliance with Network Rail Standard NR/L2/TRK/3203. To ensure the safe passage of trains surveys are carried out as part of the suite of gauging standards which manage risk relating to gauging compatibility, structural clearances, passing clearances and calculation of stepping clearances on the infrastructure.
All gauging surveys are carried out with the latest compliant equipment; utilising track mounted Abtus Routescans, Balfour Beatty Lasersweep, Robel Platform Gages and track mounted laser scanners on Track Measuring devices (TMDs). Gauging surveys include rail geometry collected from both TMDs and conventional topographical methods.
The Permanent Way Design team within PBH Rail offer full clearance analysis through ClearRoute; providing Network Rail National Gauging Database reports.
