ZARR utilises ground penetrating radar (GPR) and is a uniquely powerful desk study tool to continuously map changes in the thickness and quality of the ballast layer across a network.

The ZARR is a unique trackbed maintenance planning solution, providing:

– Ballast fouling index (BFI) to a specified depth– Accurate ballast layer depth profiles– Location of ballast pockets and wet beds– Extent of formation failures– Integration with track geometry
