Track measurement

TRACKSCAN METRO

LASER MEASUREMENT TECHNOLOGY FOR TRACK GEOMETRY AND THIRD RAILS

Goldschmidt´s Trackscan Metro trolley is designed to measure the track geometry together with the measurement of the rail cross profile and current power rail position on both sides of the tracks. The measurement results can be read directly on the trolley’s display and save in memory. The Dari® software supplied with the trolley allows the user to further analyse the measurement results and generate different kind of reports.

The trolley is supplied with the Dari® software (for PCs) enabling, among other things, the graphic presentation and comparison of measurement results as well as the printing of measurement reports or calculating typical track quality factors. Measurement results are also available in the tabular form containing track defect locations. Measurement data can be exported in MS Word, MS Excel and PDF formats.

In addition, the software enables the saving of measured profiles in the DXF format, comparing measured profiles with model profiles, automatic sizing and printing of rail profile-related reports.
