The track you cannot see is the track that fails first
Most rail failures start below the rail — in fouled ballast that no longer drains, in trapped water softening the subgrade, in thinning clean-ballast layers nobody measured. KHEERAN exists to make the invisible part of the railway visible.
Ballast investigation with multi-frequency GPR (400 MHz–2 GHz).
Rail track geometry measurement and deterioration trending.
Railway asset scanning and clearance mapping with LiDAR.
Science first. Field-practical. Decision-ready.
Specialist rail infrastructure diagnostics for railways, transit authorities and contractors
Our crews mount multi-frequency GPR, geometry and LiDAR systems on hi-rail vehicles and survey your track at normal hi-rail speed. Data is processed with methods validated by the FRA, the Transportation Technology Center and leading university research groups — and calibrated against samples of your own ballast.
We deliver continuous, georeferenced pictures of your track — above and below the ballast line
Fouling categories by chainage. Clean-ballast thickness. Trapped water. Geometry exceptions. Asset inventories and clearances. Reports your planners can take into a budget meeting unedited.

Ballast Investigation with GPR
Continuous mapping of ballast fouling, clean-ballast thickness and trapped water — calibrated to your ballast and reported by chainage.
Rail Track Geometry
Geometry scanning that locates gauge, alignment, twist and surface defects — and ties faults back to their substructure causes.
Railway Asset Scanning with LiDAR
High-density LiDAR capture of track assets, structures and clearances for inventory, condition assessment and 3D modelling.
