Zetica, a company that develops innovative train-mounted advanced rail radar systems, has recently released two free white papers, which explain the company’s products and services – ZARR and its holistic strategy for inspecting track beds.

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.

Significant changes can occur at different stages in the lifetime of a ballasted trackbed under repeated loading. These include, but are not limited to, the generation of fines, which may clog ballast void space, the failure of the formation leading to ingress of fines through pumping and localised settlement of the formation leading to the growth of ballast pockets.
