The TSC trolley measures track geometry. The measurement
results include values of track gauge, cant, horizontal and vertical irregularities along with the calculated gradient and twist parameters.

Back to the listTRACK CART FOR TRACK GEOMETRY AND RAIL WEAR MEASUREMENT
The Trackscan Cadd-e trolley is equipped with the laser inertial non-contact measurement system. The system measures track geometry parameters and both rail cross-section profiles, calculating the rail head wear. A built-in GPS controller provides information on the measurementroute.
The device meets requirements of the EN 13848 - 4 standard
Dedicated PC software delivered with the system makes it possible to carry out extensive measurement data analysis and reporting.

Built-in functionality allows the user to compare measurements taken at different periods of time. All measurements are presented in the form of graphs with selected parameters exceeding the specified tolerance, there are also icons showing track defects observed by trolley operators during measurements. Track geometry reports can be saved in Word, Excel, PDF, CSV formats. The software enables exporting data and printing reports. The standard version of the software provides capabilities of generating reports for:
- Charting measurement data,
- The report numerical measurement results,
- The report defects,
-
The report performance indicators.

The system allows the measurement of the rail head cross-section. Measured results are automatically analyzed and parameters of wear are automatically calculated. The results of these calculations are presented in the form of graphs.
The software makes it possible to perform detailed analysis of selected cross-sections and compare them with nominal profiles. Results of railhead wear analyzes can be printed as reports or saved to DXF files.

The trolley memory size is big enough to store up to 56 000 km of track geometry data or railhead profiles from 260 km length. Saved measurements are copied to the office system via the USB port.
