Effective railway maintenance planning starts with accurate, continuous condition data. KHEERAN Corporation’s GPR inspection data gives railway maintenance teams the substructure intelligence they need to plan tamping, undercutting, ballast cleaning, and track renewal with precision and confidence. As a result, maintenance budgets deliver maximum track performance improvement per dollar spent.
Railway Maintenance Planning with GPR Data: The Advantage
Traditional maintenance planning relies on visual inspection and isolated trial pit results. However, these sources provide incomplete condition data. Furthermore, visual inspection misses substructure deterioration that has not yet appeared as a geometry defect. As a result, maintenance resources are often misallocated — either too early on sections that did not need intervention, or too late on sections already seriously deteriorated. Therefore, continuous GPR data changes the picture entirely.
Continuous, Georeferenced Condition Intelligence
KHEERAN’s multi-frequency GPR covers every metre of the surveyed corridor. Furthermore, continuous fouling maps, clean ballast thickness profiles, and moisture identification are all georeferenced and GIS-compatible. Consequently, maintenance planning teams overlay GPR data against geometry records, tamping history, and renewal schedules in a single asset management view. As a result, decisions are based on the full picture — not fragmented data from separate sources.
Supporting the Full Maintenance Lifecycle
Additionally, KHEERAN’s GPR data supports every maintenance decision type. It optimises tamping intervals by identifying sections that genuinely need attention. Moreover, it prioritises undercutting programs by ranking fouling severity. Furthermore, capital renewal programs are targeted at sections where substructure condition justifies the investment.

Industry Standards Behind Railway Maintenance Planning with GPR Inspection Data
KHEERAN’s railway maintenance planning GPR inspection data methodology aligns with guidance from AREMA, the Federal Railroad Administration (FRA), and Transport Canada. Furthermore, ballast condition classification using the Selig Fouling Index provides a consistent, internationally recognised basis for maintenance priority decisions. Additionally, KHEERAN’s GPR inspection data is delivered in formats compatible with railway asset management and maintenance planning systems. Consequently, railway maintenance teams can integrate GPR inspection data directly into tamping, undercutting, and renewal planning workflows — without additional data processing or engineering interpretation.
