Developed in partnership with Amberg Technologies, Pandrol’s GeoVizio-TR-Smart is a new smart track geometry trolley for measuring the quality of track. It is an innovative track geometry trolley that quantifies the condition of track and determines Track Quality Index, as required in the new European Standard EN 13848-6.
The GeoVizio-TR-Smart measures the evolution of the track through five main parameters: gauge, cant, twist, longitudinal level and alignment. It comes with a tablet and software for data recording and analysis, which allows the determination of Track Quality Index (TQI), as required in the new European Standard EN 13848-6 (Characterisation of track geometry quality).
The GeoVizio-TR-Smart’s versatility means that it can be used for several gauges, thanks to a removable gauge extension
Weighing just 25kg, the GeoVizio-TR-Smart is easy for a single operator to use and move on and off track.
Supplied with two batteries, the trolley has a long battery autonomy – it can be used for three days before it needs recharging
The trolley can be dismantled into three parts for ease of transportation.
Double data backup and high storage capacity ensure the security of data collected.
The trolley is robust and durable, with anti-wear ceramic side guards for extra protection.
The relative track position is measured with the aid of an inertial measurement unit.
The GeoVizio-TR-Smart provides graphical and numerical reports on track gauge measurements, including threshold monitoring and visualisation. Deviation to nominal gauge is in a predefined requested interval. Curves and sections with gauge access are taken into consideration.
The trolley also provides graphical and numerical reports on cross-level measurements, including cant and derived twist values. The cant measurement is deviation to nominal cant. The twist calculation is based on different, configurable twist calculation base lengths.
Longitudinal level and alignment are assessed, including threshold monitoring and verification that considers track and line characteristics. The maintenance and safety thresholds are ‘alert’, ‘intervention’ and ‘immediate action’. The GeoVizio-TR-Smart can be used on different line and speed categories, and can also be adjusted for country-specific needs.
The GeoVizio-TR-Smart provides data and tools for further analysis of various track parameters and determination of TQI.
The IP65 trolley comes with an IP67 tablet and easy-to-use software that provides geographic information, displays values, calculates TQI and allows for the addition of comments. A version can be transcribed for reading on Google EarthTM, and geometric defects and the quality index can be shown on an offline map.
