The rail industry is committed to investing millions of pounds in improving quality through renewals and maintenance. Productivity and efficiency are key to delivering value for money during this process.
For a number of years Ground Penetrating Radar (GPR) has offered a means of potentially identifying incipient trackbed problems such as wet bed formation, ballast pumping and ballast degradation, and sub-grade failure.
Zetica has developed the innovative train-mounted Zetica Advanced Rail Radar (ZARR) system. ZARR offers the following two main benefits:
Major efficiencies and cost savings compared with existing trackbed evaluation methods: data is acquired using any measurement or in-service train platform and trackbed information can now be acquired alongside track geometry and asset mapping data.
More efficient planning and execution of trackbed maintenance through monitoring of trackbed deterioration over time, identification of sites for renewal by ballast cleaning before degradation reaches the stage where costlier machine reballasting is required, and quality control of renewals through pre- and post-renewal scanning.
The system also provides for:
Zetica also provides its Trackside service offering detailed site investigation of the rail trackbed and its surroundings.
Utilising a combination of traditional site investigation methods and non-intrusive techniques, Zetica can provide information that enables a better assessment of ballast, formation, drainage and other key trackbed conditions:
Zetica utilises GPR on road-rail (up to 30kph) or trolley platforms with targeted sampling to:
